- * possible to ensure you can claim HTLC outputs on the latest commitment transaction

- * Manager which keeps track of a number of channels and sends messages to the appropriate
- * channel, also tracking HTLC preimages and forwarding onion packets appropriately.
+ * A lightning node's channel state machine and payment management logic, which facilitates
+ * sending, forwarding, and receiving payments through lightning channels.
+ *
+ * [`ChannelManager`] is parameterized by a number of components to achieve this.
+ * - [`chain::Watch`] (typically [`ChainMonitor`]) for on-chain monitoring and enforcement of each
+ * channel
+ * - [`BroadcasterInterface`] for broadcasting transactions related to opening, funding, and
+ * closing channels
+ * - [`EntropySource`] for providing random data needed for cryptographic operations
+ * - [`NodeSigner`] for cryptographic operations scoped to the node
+ * - [`SignerProvider`] for providing signers whose operations are scoped to individual channels
+ * - [`FeeEstimator`] to determine transaction fee rates needed to have a transaction mined in a
+ * timely manner
+ * - [`Router`] for finding payment paths when initiating and retrying payments
+ * - [`Logger`] for logging operational information of varying degrees
+ *
+ * Additionally, it implements the following traits:
+ * - [`ChannelMessageHandler`] to handle off-chain channel activity from peers
+ * - [`MessageSendEventsProvider`] to similarly send such messages to peers
+ * - [`OffersMessageHandler`] for BOLT 12 message handling and sending
+ * - [`EventsProvider`] to generate user-actionable [`Event`]s
+ * - [`chain::Listen`] and [`chain::Confirm`] for notification of on-chain activity
+ *
+ * Thus, [`ChannelManager`] is typically used to parameterize a [`MessageHandler`] and an
+ * [`OnionMessenger`]. The latter is required to support BOLT 12 functionality.
+ *
+ * # `ChannelManager` vs `ChannelMonitor`
+ *
+ * It's important to distinguish between the *off-chain* management and *on-chain* enforcement of
+ * lightning channels. [`ChannelManager`] exchanges messages with peers to manage the off-chain
+ * state of each channel. During this process, it generates a [`ChannelMonitor`] for each channel
+ * and a [`ChannelMonitorUpdate`] for each relevant change, notifying its parameterized
+ * [`chain::Watch`] of them.
+ *
+ * An implementation of [`chain::Watch`], such as [`ChainMonitor`], is responsible for aggregating
+ * these [`ChannelMonitor`]s and applying any [`ChannelMonitorUpdate`]s to them. It then monitors
+ * for any pertinent on-chain activity, enforcing claims as needed.
+ *
+ * This division of off-chain management and on-chain enforcement allows for interesting node
+ * setups. For instance, on-chain enforcement could be moved to a separate host or have added
+ * redundancy, possibly as a watchtower. See [`chain::Watch`] for the relevant interface.
+ *
+ * # Initialization
+ *
+ * Use [`ChannelManager::new`] with the most recent [`BlockHash`] when creating a fresh instance.
+ * Otherwise, if restarting, construct [`ChannelManagerReadArgs`] with the necessary parameters and
+ * references to any deserialized [`ChannelMonitor`]s that were previously persisted. Use this to
+ * deserialize the [`ChannelManager`] and feed it any new chain data since it was last online, as
+ * detailed in the [`ChannelManagerReadArgs`] documentation.

+ * }
+ * # Ok(())
+ * # }
+ * ```
+ *
+ * # Operation
+ *
+ * The following is required for [`ChannelManager`] to function properly:
+ * - Handle messages from peers using its [`ChannelMessageHandler`] implementation (typically
+ * called by [`PeerManager::read_event`] when processing network I/O)
+ * - Send messages to peers obtained via its [`MessageSendEventsProvider`] implementation
+ * (typically initiated when [`PeerManager::process_events`] is called)
+ * - Feed on-chain activity using either its [`chain::Listen`] or [`chain::Confirm`] implementation
+ * as documented by those traits
+ * - Perform any periodic channel and payment checks by calling [`timer_tick_occurred`] roughly
+ * every minute
+ * - Persist to disk whenever [`get_and_clear_needs_persistence`] returns `true` using a
+ * [`Persister`] such as a [`KVStore`] implementation
+ * - Handle [`Event`]s obtained via its [`EventsProvider`] implementation
+ *
+ * The [`Future`] returned by [`get_event_or_persistence_needed_future`] is useful in determining
+ * when the last two requirements need to be checked.
+ *
+ * The [`lightning-block-sync`] and [`lightning-transaction-sync`] crates provide utilities that
+ * simplify feeding in on-chain activity using the [`chain::Listen`] and [`chain::Confirm`] traits,
+ * respectively. The remaining requirements can be met using the [`lightning-background-processor`]
+ * crate. For languages other than Rust, the availability of similar utilities may vary.
+ *
+ * # Channels
+ *
+ * [`ChannelManager`]'s primary function involves managing a channel state. Without channels,
+ * payments can't be sent. Use [`list_channels`] or [`list_usable_channels`] for a snapshot of the
+ * currently open channels.
+ *
+ * ```
+ * # use lightning::ln::channelmanager::AChannelManager;
+ * #
+ * # fn example<T: AChannelManager>(channel_manager: T) {
+ * # let channel_manager = channel_manager.get_cm();
+ * let channels = channel_manager.list_usable_channels();
+ * for details in channels {
+ * println!(\"{:?}\", details);
+ * }
+ * # }
+ * ```
+ *
+ * Each channel is identified using a [`ChannelId`], which will change throughout the channel's
+ * life cycle. Additionally, channels are assigned a `user_channel_id`, which is given in
+ * [`Event`]s associated with the channel and serves as a fixed identifier but is otherwise unused
+ * by [`ChannelManager`].
+ *
+ * ## Opening Channels
+ *
+ * To an open a channel with a peer, call [`create_channel`]. This will initiate the process of
+ * opening an outbound channel, which requires self-funding when handling
+ * [`Event::FundingGenerationReady`].
+ *
+ * ```
+ * # use bitcoin::{ScriptBuf, Transaction};
+ * # use bitcoin::secp256k1::PublicKey;
+ * # use lightning::ln::channelmanager::AChannelManager;
+ * # use lightning::events::{Event, EventsProvider};
+ * #
+ * # trait Wallet {
+ * # fn create_funding_transaction(
+ * # &self, _amount_sats: u64, _output_script: ScriptBuf
+ * # ) -> Transaction;
+ * # }
+ * #
+ * # fn example<T: AChannelManager, W: Wallet>(channel_manager: T, wallet: W, peer_id: PublicKey) {
+ * # let channel_manager = channel_manager.get_cm();
+ * let value_sats = 1_000_000;
+ * let push_msats = 10_000_000;
+ * match channel_manager.create_channel(peer_id, value_sats, push_msats, 42, None, None) {
+ * Ok(channel_id) => println!(\"Opening channel {}\", channel_id),
+ * Err(e) => println!(\"Error opening channel: {:?}\", e),
+ * }
+ *
+ * // On the event processing thread once the peer has responded
+ * channel_manager.process_pending_events(&|event| match event {
+ * Event::FundingGenerationReady {
+ * temporary_channel_id, counterparty_node_id, channel_value_satoshis, output_script,
+ * user_channel_id, ..
+ * } => {
+ * assert_eq!(user_channel_id, 42);
+ * let funding_transaction = wallet.create_funding_transaction(
+ * channel_value_satoshis, output_script
+ * );
+ * match channel_manager.funding_transaction_generated(
+ * &temporary_channel_id, &counterparty_node_id, funding_transaction
+ * ) {
+ * Ok(()) => println!(\"Funding channel {}\", temporary_channel_id),
+ * Err(e) => println!(\"Error funding channel {}: {:?}\", temporary_channel_id, e),
+ * }
+ * },
+ * Event::ChannelPending { channel_id, user_channel_id, former_temporary_channel_id, .. } => {
+ * assert_eq!(user_channel_id, 42);
+ * println!(
+ * \"Channel {} now {} pending (funding transaction has been broadcasted)\", channel_id,
+ * former_temporary_channel_id.unwrap()
+ * );
+ * },
+ * Event::ChannelReady { channel_id, user_channel_id, .. } => {
+ * assert_eq!(user_channel_id, 42);
+ * println!(\"Channel {} ready\", channel_id);
+ * },
+ * // ...
+ * # _ => {},
+ * });
+ * # }
+ * ```
+ *
+ * ## Accepting Channels
*
- * Implements [`ChannelMessageHandler`], handling the multi-channel parts and passing things through
- * to individual Channels.
+ * Inbound channels are initiated by peers and are automatically accepted unless [`ChannelManager`]
+ * has [`UserConfig::manually_accept_inbound_channels`] set. In that case, the channel may be
+ * either accepted or rejected when handling [`Event::OpenChannelRequest`].
+ *
+ * ```
+ * # use bitcoin::secp256k1::PublicKey;
+ * # use lightning::ln::channelmanager::AChannelManager;
+ * # use lightning::events::{Event, EventsProvider};
+ * #
+ * # fn is_trusted(counterparty_node_id: PublicKey) -> bool {
+ * # // ...
+ * # unimplemented!()
+ * # }
+ * #
+ * # fn example<T: AChannelManager>(channel_manager: T) {
+ * # let channel_manager = channel_manager.get_cm();
+ * channel_manager.process_pending_events(&|event| match event {
+ * Event::OpenChannelRequest { temporary_channel_id, counterparty_node_id, .. } => {
+ * if !is_trusted(counterparty_node_id) {
+ * match channel_manager.force_close_without_broadcasting_txn(
+ * &temporary_channel_id, &counterparty_node_id
+ * ) {
+ * Ok(()) => println!(\"Rejecting channel {}\", temporary_channel_id),
+ * Err(e) => println!(\"Error rejecting channel {}: {:?}\", temporary_channel_id, e),
+ * }
+ * return;
+ * }
+ *
+ * let user_channel_id = 43;
+ * match channel_manager.accept_inbound_channel(
+ * &temporary_channel_id, &counterparty_node_id, user_channel_id
+ * ) {
+ * Ok(()) => println!(\"Accepting channel {}\", temporary_channel_id),
+ * Err(e) => println!(\"Error accepting channel {}: {:?}\", temporary_channel_id, e),
+ * }
+ * },
+ * // ...
+ * # _ => {},
+ * });
+ * # }
+ * ```
+ *
+ * ## Closing Channels
+ *
+ * There are two ways to close a channel: either cooperatively using [`close_channel`] or
+ * unilaterally using [`force_close_broadcasting_latest_txn`]. The former is ideal as it makes for
+ * lower fees and immediate access to funds. However, the latter may be necessary if the
+ * counterparty isn't behaving properly or has gone offline. [`Event::ChannelClosed`] is generated
+ * once the channel has been closed successfully.
+ *
+ * ```
+ * # use bitcoin::secp256k1::PublicKey;
+ * # use lightning::ln::types::ChannelId;
+ * # use lightning::ln::channelmanager::AChannelManager;
+ * # use lightning::events::{Event, EventsProvider};
+ * #
+ * # fn example<T: AChannelManager>(
+ * # channel_manager: T, channel_id: ChannelId, counterparty_node_id: PublicKey
+ * # ) {
+ * # let channel_manager = channel_manager.get_cm();
+ * match channel_manager.close_channel(&channel_id, &counterparty_node_id) {
+ * Ok(()) => println!(\"Closing channel {}\", channel_id),
+ * Err(e) => println!(\"Error closing channel {}: {:?}\", channel_id, e),
+ * }
+ *
+ * // On the event processing thread
+ * channel_manager.process_pending_events(&|event| match event {
+ * Event::ChannelClosed { channel_id, user_channel_id, .. } => {
+ * assert_eq!(user_channel_id, 42);
+ * println!(\"Channel {} closed\", channel_id);
+ * },
+ * // ...
+ * # _ => {},
+ * });
+ * # }
+ * ```
+ *
+ * # Payments
+ *
+ * [`ChannelManager`] is responsible for sending, forwarding, and receiving payments through its
+ * channels. A payment is typically initiated from a [BOLT 11] invoice or a [BOLT 12] offer, though
+ * spontaneous (i.e., keysend) payments are also possible. Incoming payments don't require
+ * maintaining any additional state as [`ChannelManager`] can reconstruct the [`PaymentPreimage`]
+ * from the [`PaymentSecret`]. Sending payments, however, require tracking in order to retry failed
+ * HTLCs.
+ *
+ * After a payment is initiated, it will appear in [`list_recent_payments`] until a short time
+ * after either an [`Event::PaymentSent`] or [`Event::PaymentFailed`] is handled. Failed HTLCs
+ * for a payment will be retried according to the payment's [`Retry`] strategy or until
+ * [`abandon_payment`] is called.
+ *
+ * ## BOLT 11 Invoices
+ *
+ * The [`lightning-invoice`] crate is useful for creating BOLT 11 invoices. Specifically, use the
+ * functions in its `utils` module for constructing invoices that are compatible with
+ * [`ChannelManager`]. These functions serve as a convenience for building invoices with the
+ * [`PaymentHash`] and [`PaymentSecret`] returned from [`create_inbound_payment`]. To provide your
+ * own [`PaymentHash`], use [`create_inbound_payment_for_hash`] or the corresponding functions in
+ * the [`lightning-invoice`] `utils` module.
+ *
+ * [`ChannelManager`] generates an [`Event::PaymentClaimable`] once the full payment has been
+ * received. Call [`claim_funds`] to release the [`PaymentPreimage`], which in turn will result in
+ * an [`Event::PaymentClaimed`].
+ *
+ * ```
+ * # use lightning::events::{Event, EventsProvider, PaymentPurpose};
+ * # use lightning::ln::channelmanager::AChannelManager;
+ * #
+ * # fn example<T: AChannelManager>(channel_manager: T) {
+ * # let channel_manager = channel_manager.get_cm();
+ * // Or use utils::create_invoice_from_channelmanager
+ * let known_payment_hash = match channel_manager.create_inbound_payment(
+ * Some(10_000_000), 3600, None
+ * ) {
+ * Ok((payment_hash, _payment_secret)) => {
+ * println!(\"Creating inbound payment {}\", payment_hash);
+ * payment_hash
+ * },
+ * Err(()) => panic!(\"Error creating inbound payment\"),
+ * };
+ *
+ * // On the event processing thread
+ * channel_manager.process_pending_events(&|event| match event {
+ * Event::PaymentClaimable { payment_hash, purpose, .. } => match purpose {
+ * PaymentPurpose::Bolt11InvoicePayment { payment_preimage: Some(payment_preimage), .. } => {
+ * assert_eq!(payment_hash, known_payment_hash);
+ * println!(\"Claiming payment {}\", payment_hash);
+ * channel_manager.claim_funds(payment_preimage);
+ * },
+ * PaymentPurpose::Bolt11InvoicePayment { payment_preimage: None, .. } => {
+ * println!(\"Unknown payment hash: {}\", payment_hash);
+ * },
+ * PaymentPurpose::SpontaneousPayment(payment_preimage) => {
+ * assert_ne!(payment_hash, known_payment_hash);
+ * println!(\"Claiming spontaneous payment {}\", payment_hash);
+ * channel_manager.claim_funds(payment_preimage);
+ * },
+ * // ...
+ * # _ => {},
+ * },
+ * Event::PaymentClaimed { payment_hash, amount_msat, .. } => {
+ * assert_eq!(payment_hash, known_payment_hash);
+ * println!(\"Claimed {} msats\", amount_msat);
+ * },
+ * // ...
+ * # _ => {},
+ * });
+ * # }
+ * ```
+ *
+ * For paying an invoice, [`lightning-invoice`] provides a `payment` module with convenience
+ * functions for use with [`send_payment`].
+ *
+ * ```
+ * # use lightning::events::{Event, EventsProvider};
+ * # use lightning::ln::types::PaymentHash;
+ * # use lightning::ln::channelmanager::{AChannelManager, PaymentId, RecentPaymentDetails, RecipientOnionFields, Retry};
+ * # use lightning::routing::router::RouteParameters;
+ * #
+ * # fn example<T: AChannelManager>(
+ * # channel_manager: T, payment_hash: PaymentHash, recipient_onion: RecipientOnionFields,
+ * # route_params: RouteParameters, retry: Retry
+ * # ) {
+ * # let channel_manager = channel_manager.get_cm();
+ * // let (payment_hash, recipient_onion, route_params) =
+ * // payment::payment_parameters_from_invoice(&invoice);
+ * let payment_id = PaymentId([42; 32]);
+ * match channel_manager.send_payment(
+ * payment_hash, recipient_onion, payment_id, route_params, retry
+ * ) {
+ * Ok(()) => println!(\"Sending payment with hash {}\", payment_hash),
+ * Err(e) => println!(\"Failed sending payment with hash {}: {:?}\", payment_hash, e),
+ * }
+ *
+ * let expected_payment_id = payment_id;
+ * let expected_payment_hash = payment_hash;
+ * assert!(
+ * channel_manager.list_recent_payments().iter().find(|details| matches!(
+ * details,
+ * RecentPaymentDetails::Pending {
+ * payment_id: expected_payment_id,
+ * payment_hash: expected_payment_hash,
+ * ..
+ * }
+ * )).is_some()
+ * );
+ *
+ * // On the event processing thread
+ * channel_manager.process_pending_events(&|event| match event {
+ * Event::PaymentSent { payment_hash, .. } => println!(\"Paid {}\", payment_hash),
+ * Event::PaymentFailed { payment_hash, .. } => println!(\"Failed paying {}\", payment_hash),
+ * // ...
+ * # _ => {},
+ * });
+ * # }
+ * ```
+ *
+ * ## BOLT 12 Offers
+ *
+ * The [`offers`] module is useful for creating BOLT 12 offers. An [`Offer`] is a precursor to a
+ * [`Bolt12Invoice`], which must first be requested by the payer. The interchange of these messages
+ * as defined in the specification is handled by [`ChannelManager`] and its implementation of
+ * [`OffersMessageHandler`]. However, this only works with an [`Offer`] created using a builder
+ * returned by [`create_offer_builder`]. With this approach, BOLT 12 offers and invoices are
+ * stateless just as BOLT 11 invoices are.
+ *
+ * ```
+ * # use lightning::events::{Event, EventsProvider, PaymentPurpose};
+ * # use lightning::ln::channelmanager::AChannelManager;
+ * # use lightning::offers::parse::Bolt12SemanticError;
+ * #
+ * # fn example<T: AChannelManager>(channel_manager: T) -> Result<(), Bolt12SemanticError> {
+ * # let channel_manager = channel_manager.get_cm();
+ * let offer = channel_manager
+ * .create_offer_builder()?
+ * # ;
+ * # // Needed for compiling for c_bindings
+ * # let builder: lightning::offers::offer::OfferBuilder<_, _> = offer.into();
+ * # let offer = builder
+ * .description(\"coffee\".to_string())
+ * .amount_msats(10_000_000)
+ * .build()?;
+ * let bech32_offer = offer.to_string();
+ *
+ * // On the event processing thread
+ * channel_manager.process_pending_events(&|event| match event {
+ * Event::PaymentClaimable { payment_hash, purpose, .. } => match purpose {
+ * PaymentPurpose::Bolt12OfferPayment { payment_preimage: Some(payment_preimage), .. } => {
+ * println!(\"Claiming payment {}\", payment_hash);
+ * channel_manager.claim_funds(payment_preimage);
+ * },
+ * PaymentPurpose::Bolt12OfferPayment { payment_preimage: None, .. } => {
+ * println!(\"Unknown payment hash: {}\", payment_hash);
+ * },
+ * // ...
+ * # _ => {},
+ * },
+ * Event::PaymentClaimed { payment_hash, amount_msat, .. } => {
+ * println!(\"Claimed {} msats\", amount_msat);
+ * },
+ * // ...
+ * # _ => {},
+ * });
+ * # Ok(())
+ * # }
+ * ```
+ *
+ * Use [`pay_for_offer`] to initiated payment, which sends an [`InvoiceRequest`] for an [`Offer`]
+ * and pays the [`Bolt12Invoice`] response. In addition to success and failure events,
+ * [`ChannelManager`] may also generate an [`Event::InvoiceRequestFailed`].
+ *
+ * ```
+ * # use lightning::events::{Event, EventsProvider};
+ * # use lightning::ln::channelmanager::{AChannelManager, PaymentId, RecentPaymentDetails, Retry};
+ * # use lightning::offers::offer::Offer;
+ * #
+ * # fn example<T: AChannelManager>(
+ * # channel_manager: T, offer: &Offer, quantity: Option<u64>, amount_msats: Option<u64>,
+ * # payer_note: Option<String>, retry: Retry, max_total_routing_fee_msat: Option<u64>
+ * # ) {
+ * # let channel_manager = channel_manager.get_cm();
+ * let payment_id = PaymentId([42; 32]);
+ * match channel_manager.pay_for_offer(
+ * offer, quantity, amount_msats, payer_note, payment_id, retry, max_total_routing_fee_msat
+ * ) {
+ * Ok(()) => println!(\"Requesting invoice for offer\"),
+ * Err(e) => println!(\"Unable to request invoice for offer: {:?}\", e),
+ * }
+ *
+ * // First the payment will be waiting on an invoice
+ * let expected_payment_id = payment_id;
+ * assert!(
+ * channel_manager.list_recent_payments().iter().find(|details| matches!(
+ * details,
+ * RecentPaymentDetails::AwaitingInvoice { payment_id: expected_payment_id }
+ * )).is_some()
+ * );
+ *
+ * // Once the invoice is received, a payment will be sent
+ * assert!(
+ * channel_manager.list_recent_payments().iter().find(|details| matches!(
+ * details,
+ * RecentPaymentDetails::Pending { payment_id: expected_payment_id, .. }
+ * )).is_some()
+ * );
+ *
+ * // On the event processing thread
+ * channel_manager.process_pending_events(&|event| match event {
+ * Event::PaymentSent { payment_id: Some(payment_id), .. } => println!(\"Paid {}\", payment_id),
+ * Event::PaymentFailed { payment_id, .. } => println!(\"Failed paying {}\", payment_id),
+ * Event::InvoiceRequestFailed { payment_id, .. } => println!(\"Failed paying {}\", payment_id),
+ * // ...
+ * # _ => {},
+ * });
+ * # }
+ * ```
+ *
+ * ## BOLT 12 Refunds
+ *
+ * A [`Refund`] is a request for an invoice to be paid. Like *paying* for an [`Offer`], *creating*
+ * a [`Refund`] involves maintaining state since it represents a future outbound payment.
+ * Therefore, use [`create_refund_builder`] when creating one, otherwise [`ChannelManager`] will
+ * refuse to pay any corresponding [`Bolt12Invoice`] that it receives.
+ *
+ * ```
+ * # use core::time::Duration;
+ * # use lightning::events::{Event, EventsProvider};
+ * # use lightning::ln::channelmanager::{AChannelManager, PaymentId, RecentPaymentDetails, Retry};
+ * # use lightning::offers::parse::Bolt12SemanticError;
+ * #

* Implements [`Writeable`] to write out all channel state to disk. Implies [`peer_disconnected`] for
* all peers during write/read (though does not modify this instance, only the instance being
* called [`funding_transaction_generated`] for outbound channels) being closed.
*
* Note that you can be a bit lazier about writing out `ChannelManager` than you can be with
- * [`ChannelMonitor`]. With [`ChannelMonitor`] you MUST write each monitor update out to disk before
- * returning from [`chain::Watch::watch_channel`]/[`update_channel`], with ChannelManagers, writing updates
- * happens out-of-band (and will prevent any other `ChannelManager` operations from occurring during
- * the serialization process). If the deserialized version is out-of-date compared to the
- * [`ChannelMonitor`] passed by reference to [`read`], those channels will be force-closed based on the
- * `ChannelMonitor` state and no funds will be lost (mod on-chain transaction fees).
+ * [`ChannelMonitor`]. With [`ChannelMonitor`] you MUST durably write each
+ * [`ChannelMonitorUpdate`] before returning from
+ * [`chain::Watch::watch_channel`]/[`update_channel`] or before completing async writes. With
+ * `ChannelManager`s, writing updates happens out-of-band (and will prevent any other
+ * `ChannelManager` operations from occurring during the serialization process). If the
+ * deserialized version is out-of-date compared to the [`ChannelMonitor`] passed by reference to
+ * [`read`], those channels will be force-closed based on the `ChannelMonitor` state and no funds
+ * will be lost (modulo on-chain transaction fees).
*
* Note that the deserializer is only implemented for `(`[`BlockHash`]`, `[`ChannelManager`]`)`, which
* tells you the last block hash which was connected. You should get the best block tip before using the manager.
* See [`chain::Listen`] and [`chain::Confirm`] for more details.
*
+ * # `ChannelUpdate` Messages
+ *
* Note that `ChannelManager` is responsible for tracking liveness of its channels and generating
* [`ChannelUpdate`] messages informing peers that the channel is temporarily disabled. To avoid
* spam due to quick disconnection/reconnection, updates are not sent until the channel has been
* offline for a full minute. In order to track this, you must call
* [`timer_tick_occurred`] roughly once per minute, though it doesn't have to be perfect.
*
+ * # DoS Mitigation
+ *
* To avoid trivial DoS issues, `ChannelManager` limits the number of inbound connections and
* inbound channels without confirmed funding transactions. This may result in nodes which we do
* not have a channel with being unable to connect to us or open new channels with us if we have
* exempted from the count of unfunded channels. Similarly, outbound channels and connections are
* never limited. Please ensure you limit the count of such channels yourself.
*
+ * # Type Aliases
+ *
* Rather than using a plain `ChannelManager`, it is preferable to use either a [`SimpleArcChannelManager`]
* a [`SimpleRefChannelManager`], for conciseness. See their documentation for more details, but
* essentially you should default to using a [`SimpleRefChannelManager`], and use a
* [`SimpleArcChannelManager`] when you require a `ChannelManager` with a static lifetime, such as when
* you're using lightning-net-tokio.

+ * Implements [`Persist`] in a way that writes and reads both [`ChannelMonitor`]s and
+ * [`ChannelMonitorUpdate`]s.
+ *
+ * # Overview
+ *
+ * The main benefit this provides over the [`KVStore`]'s [`Persist`] implementation is decreased
+ * I/O bandwidth and storage churn, at the expense of more IOPS (including listing, reading, and
+ * deleting) and complexity. This is because it writes channel monitor differential updates,
+ * whereas the other (default) implementation rewrites the entire monitor on each update. For
+ * routing nodes, updates can happen many times per second to a channel, and monitors can be tens
+ * of megabytes (or more). Updates can be as small as a few hundred bytes.
+ *
+ * Note that monitors written with `MonitorUpdatingPersister` are _not_ backward-compatible with
+ * the default [`KVStore`]'s [`Persist`] implementation. They have a prepended byte sequence,
+ * [`MONITOR_UPDATING_PERSISTER_PREPEND_SENTINEL`], applied to prevent deserialization with other
+ * persisters. This is because monitors written by this struct _may_ have unapplied updates. In
+ * order to downgrade, you must ensure that all updates are applied to the monitor, and remove the
+ * sentinel bytes.
+ *
+ * # Storing monitors
+ *
+ * Monitors are stored by implementing the [`Persist`] trait, which has two functions:
+ *
+ * - [`Persist::persist_new_channel`], which persists whole [`ChannelMonitor`]s.
+ * - [`Persist::update_persisted_channel`], which persists only a [`ChannelMonitorUpdate`]
+ *
+ * Whole [`ChannelMonitor`]s are stored in the [`CHANNEL_MONITOR_PERSISTENCE_PRIMARY_NAMESPACE`],
+ * using the familiar encoding of an [`OutPoint`] (for example, `[SOME-64-CHAR-HEX-STRING]_1`).
+ *
+ * Each [`ChannelMonitorUpdate`] is stored in a dynamic secondary namespace, as follows:
+ *
+ * - primary namespace: [`CHANNEL_MONITOR_UPDATE_PERSISTENCE_PRIMARY_NAMESPACE`]
+ * - secondary namespace: [the monitor's encoded outpoint name]
+ *
+ * Under that secondary namespace, each update is stored with a number string, like `21`, which
+ * represents its `update_id` value.
+ *
+ * For example, consider this channel, named for its transaction ID and index, or [`OutPoint`]:
+ *
+ * - Transaction ID: `deadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef`
+ * - Index: `1`
+ *
+ * Full channel monitors would be stored at a single key:
+ *
+ * `[CHANNEL_MONITOR_PERSISTENCE_PRIMARY_NAMESPACE]/deadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef_1`
+ *
+ * Updates would be stored as follows (with `/` delimiting primary_namespace/secondary_namespace/key):
+ *
+ * ```text
+ * [CHANNEL_MONITOR_UPDATE_PERSISTENCE_PRIMARY_NAMESPACE]/deadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef_1/1
+ * [CHANNEL_MONITOR_UPDATE_PERSISTENCE_PRIMARY_NAMESPACE]/deadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef_1/2
+ * [CHANNEL_MONITOR_UPDATE_PERSISTENCE_PRIMARY_NAMESPACE]/deadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef_1/3
+ * ```
+ * ... and so on.
+ *
+ * # Reading channel state from storage
+ *
+ * Channel state can be reconstructed by calling
+ * [`MonitorUpdatingPersister::read_all_channel_monitors_with_updates`]. Alternatively, users can
+ * list channel monitors themselves and load channels individually using
+ * [`MonitorUpdatingPersister::read_channel_monitor_with_updates`].
+ *
+ * ## EXTREMELY IMPORTANT
+ *
+ * It is extremely important that your [`KVStore::read`] implementation uses the
+ * [`io::ErrorKind::NotFound`] variant correctly: that is, when a file is not found, and _only_ in
+ * that circumstance (not when there is really a permissions error, for example). This is because
+ * neither channel monitor reading function lists updates. Instead, either reads the monitor, and
+ * using its stored `update_id`, synthesizes update storage keys, and tries them in sequence until
+ * one is not found. All _other_ errors will be bubbled up in the function's [`Result`].
+ *
+ * # Pruning stale channel updates
+ *
+ * Stale updates are pruned when the consolidation threshold is reached according to `maximum_pending_updates`.
+ * Monitor updates in the range between the latest `update_id` and `update_id - maximum_pending_updates`
+ * are deleted.
+ * The `lazy` flag is used on the [`KVStore::remove`] method, so there are no guarantees that the deletions
+ * will complete. However, stale updates are not a problem for data integrity, since updates are
+ * only read that are higher than the stored [`ChannelMonitor`]'s `update_id`.
+ *
+ * If you have many stale updates stored (such as after a crash with pending lazy deletes), and
+ * would like to get rid of them, consider using the
+ * [`MonitorUpdatingPersister::cleanup_stale_updates`] function.

+ *

+ * calls return or asynchronously in the background.
+ *
+ * # For those implementing synchronous persistence
+ *
+ * * If persistence completes fully (including any relevant `fsync()` calls), the implementation
+ * should return [`ChannelMonitorUpdateStatus::Completed`], indicating normal channel operation
+ * should continue.
+ *
+ * * If persistence fails for some reason, implementations should consider returning
+ * [`ChannelMonitorUpdateStatus::InProgress`] and retry all pending persistence operations in
+ * the background with [`ChainMonitor::list_pending_monitor_updates`] and
+ * [`ChainMonitor::get_monitor`].
+ *
+ * Once a full [`ChannelMonitor`] has been persisted, all pending updates for that channel can
+ * be marked as complete via [`ChainMonitor::channel_monitor_updated`].
+ *
+ * If at some point no further progress can be made towards persisting the pending updates, the
+ * node should simply shut down.
+ *
+ * * If the persistence has failed and cannot be retried further (e.g. because of an outage),
+ * [`ChannelMonitorUpdateStatus::UnrecoverableError`] can be used, though this will result in
+ * an immediate panic and future operations in LDK generally failing.
+ *
+ * # For those implementing asynchronous persistence
+ *
+ * All calls should generally spawn a background task and immediately return
+ * [`ChannelMonitorUpdateStatus::InProgress`]. Once the update completes,
+ * [`ChainMonitor::channel_monitor_updated`] should be called with the corresponding
+ * [`MonitorUpdateId`].
+ *
+ * Note that unlike the direct [`chain::Watch`] interface,
+ * [`ChainMonitor::channel_monitor_updated`] must be called once for *each* update which occurs.
+ *
+ * If at some point no further progress can be made towards persisting a pending update, the node
+ * should simply shut down. Until then, the background task should either loop indefinitely, or
+ * persistence should be regularly retried with [`ChainMonitor::list_pending_monitor_updates`]
+ * and [`ChainMonitor::get_monitor`] (note that if a full monitor is persisted all pending
+ * monitor updates may be marked completed).
