Safe & Efficient Regex in Rust – Compile-Time Validation & Single Compilation

This crate contains a macro to generate a lazy Regex and perform regex validation. The code fails to compile if the regex is invalid.

Usage

This Rust crate helps prevent common pitfalls when working with regular expressions by ensuring patterns are valid at compile time and avoiding redundant compilations. It leverages the standard library OnceCell to compile regexes only once and uses a procedural macro for compile-time validation, improving both safety and performance. The only dependency in the crate if regex

Example:

use lure::regex;

// Password regex
let re = regex!("/^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).*$/");
assert!(re.is_match("Test1234ccc#"));
