11421 * Arguments for the creation of a ChannelManager that are not deserialized.
11423 * At a high-level, the process for deserializing a ChannelManager and resuming normal operation
11425 * 1) Deserialize all stored [`ChannelMonitor`]s.
11426 * 2) Deserialize the [`ChannelManager`] by filling in this struct and calling:
11427 * `<(BlockHash, ChannelManager)>::read(reader, args)`
11428 * This may result in closing some channels if the [`ChannelMonitor`] is newer than the stored
11429 * [`ChannelManager`] state to ensure no loss of funds. Thus, transactions may be broadcasted.
11430 * 3) If you are not fetching full blocks, register all relevant [`ChannelMonitor`] outpoints the
11431 * same way you would handle a [`chain::Filter`] call using
11432 * [`ChannelMonitor::get_outputs_to_watch`] and [`ChannelMonitor::get_funding_txo`].
11433 * 4) Reconnect blocks on your [`ChannelMonitor`]s.
11434 * 5) Disconnect/connect blocks on the [`ChannelManager`].
11435 * 6) Re-persist the [`ChannelMonitor`]s to ensure the latest state is on disk.
11436 * Note that if you're using a [`ChainMonitor`] for your [`chain::Watch`] implementation, you
11437 * will likely accomplish this as a side-effect of calling [`chain::Watch::watch_channel`] in
11439 * 7) Move the [`ChannelMonitor`]s into your local [`chain::Watch`]. If you're using a
11440 * [`ChainMonitor`], this is done by calling [`chain::Watch::watch_channel`].
11442 * Note that the ordering of #4-7 is not of importance, however all four must occur before you
11443 * call any other methods on the newly-deserialized [`ChannelManager`].
11445 * Note that because some channels may be closed during deserialization, it is critical that you
11446 * always deserialize only the latest version of a ChannelManager and ChannelMonitors available to
11447 * you. If you deserialize an old ChannelManager (during which force-closure transactions may be

11449 * not force-close the same channels but consider them live), you may end up revoking a state for
11450 * which you've already broadcasted the transaction.
