Function repeat 

pub const fn repeat(byte: u8) -> Repeat

🔬This is a nightly-only experimental API. (core_io #154046)

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

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