Deadyet?

lib.rs:

This package allows you to efficiently search for hex patterns in the hex representation of Decodable values.

It is intended to find and search for these patterns in unix timestamps, specifically occurences of DEAD within the timestamp but is not limited to this.

use deadyet::{to_next_dead, to_next_pattern, has_pattern, Decodable};

assert_eq!(to_next_dead(0xDEAE), 0xFFFF);
assert_eq!(to_next_dead(0xDEACFF), 1);
assert_eq!(to_next_dead(0xDEAD0), 0);
assert_eq!(to_next_dead(0xDEAC0), 0x10);

assert_eq!(to_next_pattern(0xAAAAA, 0xABBA, 0xFFFF), 0x110);

assert!(has_pattern(0xAABBAA, 0xABBA));
