-//! 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 routing::router::get_route 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 (ie
-/// called funding_transaction_generated for outbound channels).
-///
-/// Note that you can be a bit lazier about writing out ChannelManager than you can be with
-/// ChannelMonitors. With ChannelMonitors you MUST write each monitor update out to disk before
-/// returning from chain::Watch::watch_/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 If the deserialized version is out-of-date compared to the
-/// ChannelMonitors 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).
-///
-/// Note that the deserializer is only implemented for (BlockHash, ChannelManager), which
-/// tells you the last block hash which was block_connect()ed. You MUST rescan any blocks along
-/// the \"reorg path\" (ie call block_disconnected() until you get to a common block and then call
-/// block_connected() to step towards your best block) upon deserialization before using the
-/// object!
-///
-/// 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.
-///
-/// 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.

-/// 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 ChannelMonitors.
-/// 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 ChannelMonitors.
-/// 5) Disconnect/connect blocks on the ChannelManager.
-/// 6) Move the ChannelMonitors into your local chain::Watch.
-///
-/// Note that the ordering of #4-6 is not of importance, however all three 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.
