//! The top-level channel management and payment tracking stuff lives here.
//!
//! The [`ChannelManager`] is the main chunk of logic implementing the lightning protocol and is
//! responsible for tracking which channels are open, HTLCs are in flight and reestablishing those
//! upon reconnect to the relevant peer(s).
//!
//! It does not manage routing logic (see [`Router`] for that) nor does it manage constructing
//! on-chain transactions (it only monitors the chain to watch for any force-closes that might
//! imply it needs to fail HTLCs/payments/channels it manages).

/// 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.
///
/// Implements [`ChannelMessageHandler`], handling the multi-channel parts and passing things through
/// to individual Channels.
///
/// 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/// deserialized version is out-of-date compared to the [`ChannelMonitor`] passed by reference to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.
///
/// 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.
///
/// 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.
///
/// 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.

/// fields for more info.

///
/// # Avoiding Duplicate Payments
///
/// If a pending payment is currently in-flight with the same [`PaymentId`] provided, this
/// method will error with an [`APIError::InvalidRoute`]. Note, however, that once a payment
/// is no longer pending (either via [`ChannelManager::abandon_payment`], or handling of an
/// [`Event::PaymentSent`] or [`Event::PaymentFailed`]) LDK will not stop you from sending a
/// second payment with the same [`PaymentId`].
///
/// Thus, in order to ensure duplicate payments are not sent, you should implement your own
/// tracking of payments, including state to indicate once a payment has completed. Because you
/// should also ensure that [`PaymentHash`]es are not re-used, for simplicity, you should
/// consider using the [`PaymentHash`] as the key for tracking payments. In that case, the
/// [`PaymentId`] should be a copy of the [`PaymentHash`] bytes.
///
/// Additionally, in the scenario where we begin the process of sending a payment, but crash
/// before `send_payment` returns (or prior to [`ChannelMonitorUpdate`] persistence if you're
/// using [`ChannelMonitorUpdateStatus::InProgress`]), the payment may be lost on restart. See
/// [`ChannelManager::list_recent_payments`] for more information.
///
/// # Possible Error States on [`PaymentSendFailure`]
///
/// Each path may have a different return value, and [`PaymentSendFailure`] may return a `Vec` with
/// each entry matching the corresponding-index entry in the route paths, see
/// [`PaymentSendFailure`] for more info.
///
/// In general, a path may raise:
///  * [`APIError::InvalidRoute`] when an invalid route or forwarding parameter (cltv_delta, fee,
///    node public key) is specified.
///  * [`APIError::ChannelUnavailable`] if the next-hop channel is not available as it has been
///    closed, doesn't exist, or the peer is currently disconnected.
///  * [`APIError::MonitorUpdateInProgress`] if a new monitor update failure prevented sending the
///    relevant updates.
///
/// Note that depending on the type of the [`PaymentSendFailure`] the HTLC may have been
/// irrevocably committed to on our end. In such a case, do NOT retry the payment with a
/// different route unless you intend to pay twice!

/// Arguments for the creation of a ChannelManager that are not deserialized.
///
/// At a high-level, the process for deserializing a ChannelManager and resuming normal operation
/// is:
/// 1) Deserialize all stored [`ChannelMonitor`]s.
/// 2) Deserialize the [`ChannelManager`] by filling in this struct and calling:
///    `<(BlockHash, ChannelManager)>::read(reader, args)`
///    This may result in closing some channels if the [`ChannelMonitor`] is newer than the stored
///    [`ChannelManager`] state to ensure no loss of funds. Thus, transactions may be broadcasted.
/// 3) If you are not fetching full blocks, register all relevant [`ChannelMonitor`] outpoints the
///    same way you would handle a [`chain::Filter`] call using
///    [`ChannelMonitor::get_outputs_to_watch`] and [`ChannelMonitor::get_funding_txo`].
/// 4) Reconnect blocks on your [`ChannelMonitor`]s.
/// 5) Disconnect/connect blocks on the [`ChannelManager`].
/// 6) Re-persist the [`ChannelMonitor`]s to ensure the latest state is on disk.
///    Note that if you're using a [`ChainMonitor`] for your [`chain::Watch`] implementation, you
///    will likely accomplish this as a side-effect of calling [`chain::Watch::watch_channel`] in
///    the next step.
/// 7) Move the [`ChannelMonitor`]s into your local [`chain::Watch`]. If you're using a
///    [`ChainMonitor`], this is done by calling [`chain::Watch::watch_channel`].
///
/// Note that the ordering of #4-7 is not of importance, however all four must occur before you
/// call any other methods on the newly-deserialized [`ChannelManager`].
///
/// Note that because some channels may be closed during deserialization, it is critical that you
/// always deserialize only the latest version of a ChannelManager and ChannelMonitors available to
/// you. If you deserialize an old ChannelManager (during which force-closure transactions may be
/// broadcast), and then later deserialize a newer version of the same ChannelManager (which will
/// not force-close the same channels but consider them live), you may end up revoking a state for
/// which you've already broadcasted the transaction.
