+ * Note that the deserializer is only implemented for (Sha256dHash, ChannelManager), which
+ * tells you the last block hash which was block_connect()ed. You MUST rescan any blocks along

+ * 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_chan_freshness_every_min 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

- *
- * 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 If the deserialized version is out-of-date compared to the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 (Sha256dHash, 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_chan_freshness_every_min 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.
