pub const fn empty() -> EmptyⓘNotable traits for Empty
impl Read for Empty

Expand description

Constructs a new handle to an empty reader.

All reads from the returned reader will return Ok(0).

Examples

A slightly sad example of not reading anything into a buffer:

use std::io::{self, Read};

let mut buffer = String::new();
io::empty().read_to_string(&mut buffer).unwrap();
assert!(buffer.is_empty());
