Struct BytesCodec 

pub struct BytesCodec;

A simple codec that ships bytes around

Example

use bytes::Bytes;
use futures::{SinkExt, TryStreamExt};
use futures::io::Cursor;
use asynchronous_codec::{BytesCodec, Framed};

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

framed.send(Bytes::from("Hello World!")).await?;

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

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<<BytesCodec as Decoder>::Item>, <BytesCodec as Decoder>::Error>

Decode an item from the src BytesMut into an item

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

Called when the input stream reaches EOF, signaling a last attempt to decode

impl Encoder for BytesCodec

type Item<'a> = Bytes

The type of items consumed by encode

type Error = Error

The type of encoding errors.

fn encode( &mut self, src: <BytesCodec as Encoder>::Item<'_>, dst: &mut BytesMut, ) -> Result<(), <BytesCodec as Encoder>::Error>

Encodes an item into the BytesMut provided by dst.
