pub struct LinesCodec;
Expand description

A simple Codec implementation that splits up data into lines.

use futures::stream::TryStreamExt; // for lines.try_next()
use asynchronous_codec::{FramedRead, LinesCodec};

let input = "hello\nworld\nthis\nis\ndog\n".as_bytes();
let mut lines = FramedRead::new(input, LinesCodec);
while let Some(line) = lines.try_next().await? {
    println!("{}", line);
}
