[−][src]Function tokio::io::sink
pub fn sink() -> Sink
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(()) }
