-/// 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
+///
+/// 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::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::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> {

+/// # ;
+/// # // Needed for compiling for c_bindings
+/// # let builder: lightning::offers::offer::OfferBuilder<_, _> = offer.into();
+/// # let offer = builder
+/// .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!("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};

+/// # }
+/// ```
+///
+/// ## 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.
+///

+/// # `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.

+//! Functional tests for the BOLT 12 Offers payment flow.
+//!
+//! [`ChannelManager`] provides utilities to create [`Offer`]s and [`Refund`]s along with utilities
+//! to initiate and request payment for them, respectively. It also manages the payment flow via
+//! implementing [`OffersMessageHandler`]. This module tests that functionality, including the
+//! resulting [`Event`] generation.
+//!
+//! Two-node success tests use an announced channel:
+//!
+//! Alice --- Bob
+//!
+//! While two-node failure tests use an unannounced channel:
+//!
+//! Alice ... Bob
+//!
+//! Six-node tests use unannounced channels for the sender and recipient and announced channels for
+//! the rest of the network.
+//!
+//! nodes[4]
+//! / \
+//! / \
+//! / \
+//! Alice ... Bob -------- Charlie ... David
+//! \ /
+//! \ /
+//! \ /
+//! nodes[5]
+//!
+//! Unnamed nodes are needed to ensure unannounced nodes can create two-hop blinded paths.
+//!
+//! Nodes without channels are disconnected and connected as needed to ensure that deterministic
+//! blinded paths are used.

+
+* LDK previously serialized `PaymentRelay::fee_base_msat` as a u32 when it
