+/// 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`].
+///
+/// ```

+/// # }
+/// ```
+///
+/// ## 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;

+/// channel_manager.process_pending_events(&|event| {
+/// match event {
+/// Event::OpenChannelRequest { temporary_channel_id, counterparty_node_id, .. } => {

+/// }
+/// },
+/// // ...
+/// # _ => {},
+/// }
+/// Ok(())
+/// });
+/// # }
+/// ```
+///
+/// ## 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);
+/// },
+/// // ...
+/// # _ => {},
+/// }
+/// Ok(())
+/// });
+/// # }
+/// ```
+///
+/// # 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, .. } => {

+/// println!(\"Claimed {} msats\", amount_msat);
+/// },
+/// // ...
+/// # _ => {},
+/// }
+/// Ok(())
+/// });
+/// # }
+/// ```
+///
+/// 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;

+/// 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;

+/// println!(\"Failed paying {}\", payment_hash),
+/// // ...
+/// # _ => {},
+/// }
+/// Ok(())
+/// });
+/// # }
+/// ```
+///
+/// ## 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 absolute_expiry = None;
+/// let offer = channel_manager
+/// .create_offer_builder(absolute_expiry)?
+/// # ;
+/// # // 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(())
+/// });
+/// # Ok(())
+/// # }
+/// ```
+///
+/// Use [`pay_for_offer`] to initiated payment, which sends an [`InvoiceRequest`] for an [`Offer`]
+/// and pays the [`Bolt12Invoice`] response.
+///
+/// ```
+/// # use lightning::events::{Event, EventsProvider};
+/// # use lightning::ln::channelmanager::{AChannelManager, PaymentId, RecentPaymentDetails, Retry};

+/// match channel_manager.pay_for_offer(
+/// offer, quantity, amount_msats, payer_note, payment_id, retry, max_total_routing_fee_msat
+/// ) {

+/// Ok(())
+/// });
+/// # }
+/// ```
+///
+/// ## 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.
+///
+/// ```

+/// # _ => {},

+/// Ok(())
+/// });
+/// # }
+/// ```
+///
+/// # Persistence
+///
+/// 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
+/// serialized). This will result in any channels which have not yet exchanged [`funding_created`] (i.e.,
+/// 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 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
+/// many peers with unfunded channels.
+///
+/// Because it is an indication of trust, inbound channels which we've accepted as 0conf are
+/// 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.
