Crate match_cast

This is a minimal crate which implements match through different types.

Usage:

#[macro_use]
extern crate match_cast;
use std::panic;

fn main() {
    let res = panic::catch_unwind(|| {
        panic!("Oh no!");
    });

    let any = res.unwrap_err();

    let result = match_cast!( any {
        val as Option<u8> => {
            format!("Option<u8> = {:?}", val)
        },
        val as String => {
            format!("String = {:?}", val)
        },
        val as &'static str => {
            format!("&'static str = {:?}", val)
        },
    });

    assert_eq!(result.unwrap(), "&'static str = \"Oh no!\"");
}
