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 If the deserialized version is out-of-date compared to the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

+/// [`ChannelMonitor`]. With [`ChannelMonitor`] you MUST durably write each
+/// [`ChannelMonitorUpdate`] before returning from
+/// [`chain::Watch::watch_channel`]/[`update_channel`] or before completing async writes. With
+/// `ChannelManager`s, 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 [`ChannelMonitor`] passed by reference to
+/// [`read`], those channels will be force-closed based on the `ChannelMonitor` state and no funds
+/// will be lost (modulo on-chain transaction fees).
+///
+/// Note that the deserializer is only implemented for `(`[`BlockHash`]`, `[`ChannelManager`]`)`, which
+/// tells you the last block hash which was connected. You should get the best block tip before using the manager.
+/// See [`chain::Listen`] and [`chain::Confirm`] for more details.
+///
+/// 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.
+///
+/// To avoid trivial DoS issues, `ChannelManager` limits the number of inbound connections and
+/// inbound channels without confirmed funding transactions. This may result in nodes which we do
+/// not have a channel with being unable to connect to us or open new channels with us if we have
+/// many peers with unfunded channels.
+///
+/// Because it is an indication of trust, inbound channels which we've accepted as 0conf are
+/// exempted from the count of unfunded channels. Similarly, outbound channels and connections are
+/// never limited. Please ensure you limit the count of such channels yourself.
+///
+/// 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.
+/// 1) Deserialize all stored [`ChannelMonitor`]s.
+/// 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 [`ChannelMonitor`]s.
+/// 5) Disconnect/connect blocks on the [`ChannelManager`].
+/// 6) Re-persist the [`ChannelMonitor`]s to ensure the latest state is on disk.
+/// Note that if you're using a [`ChainMonitor`] for your [`chain::Watch`] implementation, you
+/// will likely accomplish this as a side-effect of calling [`chain::Watch::watch_channel`] in
+/// the next step.
+/// 7) Move the [`ChannelMonitor`]s into your local [`chain::Watch`]. If you're using a
+/// [`ChainMonitor`], this is done by calling [`chain::Watch::watch_channel`].
+///
+/// Note that the ordering of #4-7 is not of importance, however all four 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
/// 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.
