    * submitting new commitment transactions to the counterparty. Once the update(s) which failed
    * have been successfully applied, ChannelManager::channel_monitor_updated can be used to
    * restore the channel to an operational state.

    * Note that a given ChannelManager will *never* re-generate a given ChannelMonitorUpdate. If
    * you return a TemporaryFailure you must ensure that it is written to disk safely before
    * writing out the latest ChannelManager state.
    *
    * Even when a channel has been \"frozen\" updates to the ChannelMonitor can continue to occur
    * (eg if an inbound HTLC which we forwarded was claimed upstream resulting in us attempting
    * to claim it on this channel) and those updates must be applied wherever they can be. At

    * be returned to get things on-chain ASAP using only the in-memory copy. Obviously updates to
    * the channel which would invalidate previous ChannelMonitors are not made when a channel has
    * been \"frozen\".

    * channel_monitor_updated to ensure you have the latest monitor and re-enable normal channel
    * operation.
    *
    * Note that the update being processed here will not be replayed for you when you call
    * ChannelManager::channel_monitor_updated, so you must store the update itself along
    * with the persisted ChannelMonitor on your own local disk prior to returning a
    * TemporaryFailure. You may, of course, employ a journaling approach, storing only the
    * ChannelMonitorUpdate on disk without updating the monitor itself, replaying the journal at
    * reload-time.
    *
    * For deployments where a copy of ChannelMonitors and other local state are backed up in a
    * remote location (with local copies persisted immediately), it is anticipated that all
    * updates will return TemporaryFailure until the remote copies could be updated.

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 If the deserialized version is out-of-date compared to the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