  11 //! The [`ChannelManager`] is the main chunk of logic implementing the lightning protocol and is

  13 //! upon reconnect to the relevant peer(s).

  16 //! on-chain transactions (it only monitors the chain to watch for any force-closes that might
  17 //! imply it needs to fail HTLCs/payments/channels it manages).
