Macro lazy_regex_proc_macros::bytes_regex_captures

bytes_regex_captures!() { /* proc-macro */ }

Extract captured groups as a tuple of &u8

If there’s no match, the macro returns None.

If an optional group has no value, the tuple will contain b"" instead.

Example:

let (whole, name, version) = bytes_regex_captures!(
    r#"(\w+)-([0-9.]+)"#, // a literal regex
    b"This is lazy_regex-2.0!", // any expression
).unwrap();
assert_eq!(whole, b"lazy_regex-2.0");
assert_eq!(name, b"lazy_regex");
assert_eq!(version, "2.0".as_bytes());
