xor

The bytewise XOR of two slices of the same length.

Import

use helpers4::bytes::xor;

Cargo feature bytes (enabled by default). To compile only this module:

cargo add helpers4 --no-default-features --features bytes

or in Cargo.toml:

[dependencies]
helpers4 = { version = "0.0.6", default-features = false, features = ["bytes"] }

pub fn xor(a: &[u8], b: &[u8]) -> Option<Vec<u8>>

Parameter	Type	Description
`a`	`&[u8]`	The first slice.
`b`	`&[u8]`	The second slice.

Option<Vec<u8>> — A new Vec whose byte i is a[i] ^ b[i], or None when the lengths differ.

use helpers4::bytes::xor;

assert_eq!(xor(&[0b1100, 0b1010], &[0b1010, 0b1010]), Some(vec![0b0110, 0]));
assert_eq!(xor(&[1], &[1, 2]), None);
