compio_io::util

Struct Repeat

pub struct Repeat(/* private fields */);

Expand description

A reader that infinitely repeats one byte constructed via repeat.

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

§Examples

use compio_io::{self, AsyncRead, AsyncReadExt};

let (len, buffer) = compio_io::repeat(42)
    .read(Vec::with_capacity(3))
    .await
    .unwrap();

assert_eq!(buffer.as_slice(), [42, 42, 42]);
assert_eq!(len, 3);

Trait Implementations§

impl AsyncBufRead for Repeat

async fn fill_buf(&mut self) -> Result<&[u8]>
