```

```rust

use tuple_map::tuple_map;

fn f1(vec: &mut Vec) -> u32 {

    vec.push(1);

    10

}

fn f2(vec: &mut Vec) -> &'static str {

    vec.push(2);

    "hello"

}

fn f3(vec: &mut Vec) -> f32 {

    vec.push(3);

    1.2

}

let mut vec: Vec = Vec::new();

let a = tuple_map!((f1, f2, f3), f, {

    f(&mut vec)

});

assert_eq!(a, (10, "hello", 1.2));

assert_eq!(vec, vec![1, 2, 3]);
