Struct asynchronous_codec::BytesCodec

source ·
pub struct BytesCodec;
Expand description

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);
}
