Panic on Rust 1.64.0

[aisinker]

My little program build on Rust 1.64.0:

fn main(){
    Numpad0Key.press();
}

When I Running it:

thread 'main' panicked at 'cannot transmute_copy if U is larger than T', /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52\library\core\src\mem\mod.rs:1057:5

Seem like because Rust 1.64.0 add a assertion on transmute_copy: Add assertion that transmute_copy's U is not larger than T
