Provided Methods§

fn compat(self) -> Compat01As03<Self> ⓘ
where Self: Sized,

Converts a tokio-io AsyncWrite into a futures-io 0.3 AsyncWrite.

use futures::io::AsyncWriteExt;
use futures_util::compat::AsyncWrite01CompatExt;

let input = b"Hello World!";
let mut cursor = std::io::Cursor::new(Vec::with_capacity(12));

let mut writer = (&mut cursor).compat();
writer.write_all(input).await.unwrap();

assert_eq!(cursor.into_inner(), input);
