Crate futures_codec

Utilities for encoding and decoding frames using async/await.

Contains adapters to go from streams of bytes, AsyncRead and AsyncWrite, to framed streams implementing Sink and Stream. Framed streams are also known as transports.

use futures::TryStreamExt;
use futures::io::Cursor;
use futures_codec::{LinesCodec, Framed};

let io = Cursor::new(Vec::new());
let mut framed = Framed::new(io, LinesCodec);

while let Some(line) = framed.try_next().await? {
    dbg!(line);
}

Structs

Bytes	A reference counted contiguous slice of memory.
BytesCodec	A simple codec that ships bytes around
BytesMut	A unique reference to a contiguous slice of memory.
CborCodec	A codec for JSON encoding and decoding using serde_cbor Enc is the type to encode, Dec is the type to decode
Framed	A unified Stream and Sink interface to an underlying I/O object, using the Encoder and Decoder traits to encode and decode frames.
FramedRead	A Stream of messages decoded from an AsyncRead.
FramedWrite	A Sink of frames encoded to an AsyncWrite.
JsonCodec	A codec for JSON encoding and decoding using serde_json Enc is the type to encode, Dec is the type to decode
LengthCodec	A simple Codec implementation sending your data by prefixing it by its length.
LinesCodec	A simple Codec implementation that splits up data into lines.

Enums

CborCodecError	JSON Codec error enumeration
JsonCodecError	JSON Codec error enumeration

Traits

Decoder	Decoding of frames via buffers, for use with FramedRead.
Encoder	Encoding of messages as bytes, for use with FramedWrite.
