Expand description

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]);
