Suggest using next_multiple_of() instead of ((x + N-1) / N) * N or (x + N-1) & !(N-1) (for powers of two)

What it does

See title.

Similar for x.is_multiple_of(y) and x % y == 0.

Advantage

More readable and overflow checks

Drawbacks

No response

Example

let x = ((x + 3) / 4) * 4;
let y = (y + 3) & !3;
let z = z % 4 == 0;

Could be written as:

let x = x.next_multiple_of(4);
let y = y.next_multiple_of(4);
let z = z.is_multiple_of(4);

[sdroege]

There's also let z = (z & 3) == 0 for let z = z.is_multiple_of(4). And probably some other patterns I didn't think of yet.

Cf. #14292 (which wouldn't work with 3, by choice, but would work with 7).
