rustHow to use binary regex in Rust?


Rust supports regular expressions through the regex crate. To use binary regex, you need to specify the regex::bytes module.

use regex::bytes::Regex;

let re = Regex::new(b"^[0-9]+$").unwrap();
assert!(re.is_match(b"12345"));

The code above creates a binary regex that matches any sequence of one or more digits. The Regex::new function takes a byte string as its argument and returns a Regex object. The is_match method is then used to check if the given byte string matches the regex.

  • use regex::bytes::Regex: imports the Regex type from the regex::bytes module.
  • Regex::new(b"^[0-9]+$"): creates a Regex object from the given byte string.
  • is_match(b"12345"): checks if the given byte string matches the regex.
