slice

fn slice(Vec<byte> src, int start, int end) -> Vec<byte>

use bytes::{slice};

Returns a copy of src[start..end] (end exclusive), with both offsets clamped to the buffer.

Parameters#

Returns#

Vec<byte>

Contracts#

Checked according to --contracts (see Contracts).

ensures result.len() <= src.len()
ensures start < end || result.len() == 0

Examples#

use bytes::{slice};
use tests::assert;
let b: Vec<byte> = "hello";
assert!(slice(b, 1, 3).len() == 2);
assert!(slice(b, 3, 99).len() == 2);
