28 Each peer has one `MConnection` (multiplex connection) instance.
30 __multiplex__ *noun* a system or signal involving simultaneous transmission of
31 several messages along a single channel of communication.
33 Each `MConnection` handles message transmission on multiple abstract communication
34 `Channel`s. Each channel has a globally unique byte id.
35 The byte id and the relative priorities of each `Channel` are configured upon
36 initialization of the connection.
38 There are two methods for sending messages:
39 func (m MConnection) Send(chID byte, msgBytes []byte) bool {}
40 func (m MConnection) TrySend(chID byte, msgBytes []byte}) bool {}
42 `Send(chID, msgBytes)` is a blocking call that waits until `msg` is
43 successfully queued for the channel with the given id byte `chID`, or until the
44 request times out. The message `msg` is serialized using Go-Amino.
46 `TrySend(chID, msgBytes)` is a nonblocking call that returns false if the
47 channel's queue is full.
49 Inbound message bytes are handled with an onReceive callback function.
