Crate js_regexp

Ergonomic Rust bindings to the JavaScript standard built-in RegExp object

Basic usage

use js_regexp::{RegExp, Flags}

let re = RegExp::new(
    r#"(?<greeting>\w+), (?<name>\w+)"#,
    Flags::new("d").unwrap(),
)
.unwrap();

let result = re.exec("Hello, Alice!").unwrap();
let named_captures = result.captures.unwrap();
let named_captures = named_captures.get_named_captures_map();

assert_eq!("Hello, Alice", result.match_slice);
assert_eq!(0, result.match_index);
assert_eq!(12, result.match_length);
assert_eq!("Hello", named_captures.get("greeting").unwrap().slice);
assert_eq!(7, named_captures.get("name").unwrap().index);
