Function async_std::io::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 async_std::io;
use async_std::prelude::*;

let mut buffer = [0; 3];
io::repeat(0b101).read_exact(&mut buffer).await?;

assert_eq!(buffer, [0b101, 0b101, 0b101]);
