Macro move

macro_rules! move {
    ($e:expr) => { ... };
}

Like C++ std::move use &mut impl StdMove

Examples

Move resource types

let mut a = vec![1, 2, 3];
let b;
b = r#move!(a);
assert_eq!(a, []);
assert_eq!(b, [1, 2, 3]);

Trivial types

let mut n = 3;
assert_eq!(r#move!(n), 3);
assert_eq!(r#move!(n), 3);
assert_eq!(n, 3);
