Lz Stream IO
This crate provides IO abstractions over the futures::Stream
and futures::Sink
types.
Features
- A
std::io::Write
andtokio_io::AsyncWrite
implementation over afutures::Sink
(seelz_stream_io::SinkWrite
). - A
std::io::Read
andtokio_io::Async
implementation over afutures::Stream
(seelz_stream_io::StreamRead
).

This crate provides AsyncRead
and AsyncWrite
implementations for
Stream
and Sink
instances over byte buffers.
The StreamRead
and SinkWrite
types may be used like so:
extern crate bytes;
extern crate futures;
extern crate tokio_io;
extern crate lz_stream_io;
use futures::{Future, Stream, Sink};
use futures::unsync::mpsc;
use std::io::{Result as IoResult, ErrorKind as IoErrorKind};
use bytes::Bytes;
use tokio_io::io as async_io;
use lz_stream_io::{SinkWrite, StreamRead};
fn main() {
// The sink item type must implement From<&[u8]>
// The stream item type must implement AsRef<[u8]>
let (sink, stream) = mpsc::unbounded::<Bytes>();
// Both sink and stream must have an error type which std::io::Error
// can be created from
let sink = sink.sink_map_err(|_| IoErrorKind::InvalidData);
let stream = stream.map_err(|_| IoErrorKind::InvalidData);
let write = SinkWrite::new(sink);
let read = StreamRead::new(stream);
async_io::write_all(write, b"hello")
.and_then(|(write, _)| async_io::write_all(write, b" world"))
.and_then(|_| async_io::read_to_end(read, vec![]))
.and_then(|(_, bytes)| {
assert_eq!(bytes, b"hello world");
Ok(())
}).wait().unwrap();
}
