Buy me a coffee

Whether you use this project, have learned something from it, or just like it, please consider supporting it by buying me a coffee, so I can dedicate more time on open-source projects like this :)

Usage

The crate exports one macro, maybe!. It runs a block when an Option holds a value, binding the unwrapped value to the given name:

use mayhaps::maybe;

let opt = Some(5);
maybe!(val from (opt) exists {
    println!("got {}", val); // runs only when opt is Some
});

An else variant runs a second block when the Option is empty:

use mayhaps::maybe;

let opt: Option<i32> = None;
maybe!(val from (opt) exists {
    println!("got {}", val);
} else {
    println!("nothing there"); // runs when opt is None
});
