Macro switch

macro_rules! switch {
    ($input:expr; $first:expr$(, $($conditions:expr),*)? => $execute:expr$(,)?) => { ... };
    ($input:expr; $first:expr$(, $($conditions:expr),*)? => $execute:expr, _ => $execute_last:expr$(,)?) => { ... };
    ($input:expr; $first:expr$(, $($conditions:expr),*)? => $execute:expr, $($rest:expr$(, $($conditions_rest:expr),*)? => $exec:expr),+$(,)?) => { ... };
    ($input:expr; $first:expr$(, $($conditions:expr),*)? => $execute:expr, $($rest:expr$(, $($conditions_rest:expr),*)? => $exec:expr),+, _ => $execute_last:expr$(,)?) => { ... };
}

The macro used to emulate switch statements.

See the crate level docs for more.

Example

use easy_switch::switch;

let var = 30;
let matched = switch! { var;
    15 + 15 => true,
    22 => {
        println!("22?");
        false
    },
    _ => false,
};
assert!(matched);
