pub fn sink() -> Sink
Expand description
Creates an instance of an async writer which will successfully consume all data.
All calls to poll_write
on the returned instance will return
Poll::Ready(Ok(buf.len()))
and the contents of the buffer will not be
inspected.
This is an asynchronous version of std::io::sink
.
Examples
use tokio::io::{self, AsyncWriteExt};
#[tokio::main]
async fn main() -> io::Result<()> {
let buffer = vec![1, 2, 3, 5, 8];
let num_bytes = io::sink().write(&buffer).await?;
assert_eq!(num_bytes, 5);
Ok(())
}
