pub fn empty() -> Empty
Expand description
Creates a new empty async reader.
All reads from the returned reader will return Poll::Ready(Ok(0))
.
This is an asynchronous version of std::io::empty
.
Examples
A slightly sad example of not reading anything into a buffer:
use tokio::io::{self, AsyncReadExt};
#[tokio::main]
async fn main() {
let mut buffer = String::new();
io::empty().read_to_string(&mut buffer).await.unwrap();
assert!(buffer.is_empty());
}
