Proc macro to match regexes in const fns. The regex must be a string literal, but the bytes matched can be any value.
The macro expects an &[u8], but you can easily use str::as_bytes.
const fn this_crate(bytes: &[u8]) -> bool {
const_regex::match_regex!("^(meta-)*regex matching", bytes)
}
assert!(this_crate(b"meta-meta-regex matching"));
assert!(!this_crate(b"a good idea"));
