+ * 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 If the deserialized version is out-of-date compared to the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.
