regex-macro

This crate contains a little macro to generate a lazy Regex and remove some boilerplate when compiling regex expressions.

Usage

Generally you want to avoid compiling a regex multiple times. The regex crate suggests using lazy_static for this but you can also use once_cell which is what this crate uses. For example:

```rust use regex_macro::regex;

let re = regex!("[0-9a-f]+"); assert!(re.is_match("1234deadbeef")); ```

Which is equivalent to the following.

```rust use once_cell::sync::Lazy; use regex::Regex;

let re = { static RE: Lazy = Lazy::new(|| Regex::new("[0-9a-f]+").unwrap()); &*RE }; assert!(re.is_match("1234deadbeef")); ```
