bytes-inverse

A Rust library that provides order-inverting mapping for bytes. It transforms input bytes while preserving their ordinal relationships in reverse order.

1. For any input bytes a and b where a < b, the mapping guarantees map(a) > map(b).
2. For any input bytes a, the mapping guarantees unmap(map(a)) = a.

Usage

let e = bytes_inverse::map(b"");
let a = bytes_inverse::map(b"a");
assert!(e > a);

let b = bytes_inverse::map(b"b");
assert!(e > b);
assert!(a > b);

let aa = bytes_inverse::map(b"aa");
assert!(e > aa);
assert!(a > aa);
assert!(aa > b);
