  10 //!
  11 //! The [`ChannelManager`] is the main chunk of logic implementing the lightning protocol and is
  12 //! responsible for tracking which channels are open, HTLCs are in flight and reestablishing those
  13 //! upon reconnect to the relevant peer(s).

  15 //! It does not manage routing logic (see [`Router`] for that) nor does it manage constructing
  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).
