Function repeat

pub fn repeat(byte: u8) -> Repeat

Creates an instance of a reader that infinitely repeats one byte.

All reads from this reader will succeed by filling the specified buffer with the given byte.

Examples

use futures::io::{self, AsyncReadExt};

let mut buffer = [0; 3];
let mut reader = io::repeat(0b101);
reader.read_exact(&mut buffer).await.unwrap();
assert_eq!(buffer, [0b101, 0b101, 0b101]);
