This package exposes the StreamChannel interface, which represents a two-way
communication channel. Each StreamChannel exposes a Stream for receiving
data and a StreamSink for sending it.
StreamChannel helps abstract communication logic away from the underlying
protocol. For example, the test package re-uses its test suite
communication protocol for both WebSocket connections to browser suites and
Isolate connections to VM tests.
This package also contains utilities for dealing with StreamChannels and with
two-way communications in general. For documentation of these utilities, see
the API docs.
