match-utils

Macros for more involved pattern matching than the standard library allows.

Examples

You can create a matcher for multiple regex patterns using the regex_match! macro. It can handle pure matching, as well as using a fixed number of unnamed capture groups. For example:

let a = "some string to match";

regex_match! (a, {
    "^some" => println!("Starts with some!"),
    "add *(-?[0-9]+), *(-?[0-9]+)" [lhs: i32, rhs: i32] => {
        println!("Sum: {}", lval + rval);
    },
    _ => println!("Default case")
});

Type arguments can be provided, assuming that they implement the FromStr trait.
