Struct tokio_util::codec::BytesCodec

source ·
pub struct BytesCodec(/* private fields */);
Expand description

A simple Decoder and Encoder implementation that just ships bytes around.

§Example

Turn an AsyncRead into a stream of Result<BytesMut, Error>.

use tokio::fs::File;
use tokio::io::AsyncRead;
use tokio_util::codec::{FramedRead, BytesCodec};

let my_async_read = File::open("filename.txt").await?;
let my_stream_of_bytes = FramedRead::new(my_async_read, BytesCodec::new());
