How can I modify a part of bigger slice or Vec with another smaller slice?
How can I correctly implement this code below?
let mut bigger: [u8; 100] = [0u8; 100];
let smaller: [u8; 3] = [1, 2, 3];
// do something like:
// bigger[0..3] = smaller;

Use copy_from_slice:
bigger[0..3].copy_from_slice(&smaller);
