Expand description

Returns an iterator over all occurrences of the given needle in the stream.

Examples

use std::io::{self, Cursor};

fn main() -> io::Result<()> {
    let mut stream = Cursor::new(b"rusty rust");

    let mut iter = xfind::find_iter(b"rust", &mut stream);
    assert_eq!(iter.next().transpose()?, Some(0));
    assert_eq!(iter.next().transpose()?, Some(6));
    assert_eq!(iter.next().transpose()?, None);

    Ok(())
