Struct `DrainBytes`

pub struct DrainBytes<'a> { /* private fields */ }

A draining byte oriented iterator for Vec<u8>.

This iterator is created by ByteVec::drain_bytes.

Examples

Basic usage:

use bstr::ByteVec;

let mut s = Vec::from("foobar");
{
    let mut drainer = s.drain_bytes(2..4);
    assert_eq!(drainer.next(), Some(b'o'));
    assert_eq!(drainer.next(), Some(b'b'));
    assert_eq!(drainer.next(), None);
}
assert_eq!(s, "foar".as_bytes());
