9 //! The top-level channel management and payment tracking stuff lives here.
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 routing::router::get_route 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).
