Network.WebSockets.Stream

Lightweight abstraction over an input/output stream.

Create a stream from a "receive" and "send" action. The following properties apply:

• Regardless of the provided "receive" and "send" functions, reading and writing from the stream will be thread-safe, i.e. this function will create a receive and write lock to be used internally.

• Reading from or writing to a closed Stream will always throw an exception, even if the underlying "receive" and "send" functions do not (we do the bookkeeping).

• Streams should always be closed.
