Struct futures_codec::BytesCodec

pub struct BytesCodec {}

A simple codec that ships bytes around

Example

#![feature(async_await, await_macro)]
use bytes::Bytes;
use futures::{SinkExt, TryStreamExt};
use std::io::Cursor;
use futures_codec::{BytesCodec, Framed};

async move {
   let mut buf = vec![];
   // Cursor implements AsyncRead and AsyncWrite
   let cur = Cursor::new(&mut buf);
   let mut framed = Framed::new(cur, BytesCodec {});

   let msg = Bytes::from("Hello World!");
   framed.send(msg).await.unwrap();

   while let Some(msg) = framed.try_next().await.unwrap() {
       println!("{:?}", msg);
   }
};

Trait Implementations

impl Decoder for BytesCodec

type Item = Bytes

The type of items returned by decode

type Error = Error

The type of decoding errors.

fn decode(
    &mut self,
    src: &mut BytesMut
) -> Result<Option<Self::Item>, Self::Error>

Decode an item from the src BytesMut into an item

impl Encoder for BytesCodec

type Item = Bytes

The type of items consumed by encode

type Error = Error

The type of encoding errors.

fn encode(
    &mut self,
    src: Self::Item,
    dst: &mut BytesMut
) -> Result<(), Self::Error>

Encodes an item into the BytesMut provided by dst.
