mirage-channel — Buffered channels for MirageOS FLOW types

v5.0.0

Channels are buffered reader/writers built on top of unbuffered FLOW implementations.

Example:

module Channel = Channel.Make(Flow)
...
Channel.read_exactly ~len:16 t >>= function
| Error read_error
| Ok `Eof -> ...
| Ok `Data bufs -> (* read header of message *)
  let payload_length = Cstruct.(LE.get_uint16 (concat bufs) 0) in
  Channel.read_exactly ~len:payload_length t >>= function
  | Ok `Data bufs -> (* payload of message *)
  | Ok `Eof -> ...
  | Error read_error
(* process message *)

Channel.write_buffer t header;
Channel.write_buffer t payload;
Channel.flush t >>= function
| Error write_error -> ...
| Ok () -> ...
