-//! Wire messages, traits representing wire message handlers, and a few error types live here.
-//!
-//! For a normal node you probably don't need to use anything here, however, if you wish to split a
-//! node into an internet-facing route/message socket handling daemon and a separate daemon (or
-//! server entirely) which handles only channel-related messages you may wish to implement
-//! ChannelMessageHandler yourself and use it to re-serialize messages and pass them across
-//! daemons/servers.
-//!
-//! Note that if you go with such an architecture (instead of passing raw socket events to a
-//! non-internet-facing system) you trust the frontend internet-facing system to not lie about the
-//! source node_id of the mssage, however this does allow you to significantly reduce bandwidth
-//! between the systems as routing messages can represent a significant chunk of bandwidth usage
-//! (especially for non-channel-publicly-announcing nodes). As an alternate design which avoids
-//! this issue, if you have sufficient bidirectional bandwidth between your systems, you may send
-//! raw socket events into your non-internet-facing system and then send routing events back to
-//! track the network on the less-secure system.
