golang like switch in rust

main.rs

macro_rules! switch {
    ($($a:expr => $b:expr;)* _ => $e:expr $(,)?) => {
        match () {
            $(_ if $a => $b,)*
            _ => $e,
        }
    };
}

fn f1() -> bool {
    println!("f1");
    true
}

fn f2() -> bool {
    println!("f2");
    true
}

fn main() {
    switch! {
        f1() => {
            println!("match f1");
        };
        f2() => {
            println!("match f2");
        };
        _ => {}
    }
}

// Output:
// f1
// match f1

For gopher who love using switch instead of cascading if else.
