Primitive Type usize

Expand description
The pointer-sized unsigned integer type.
The size of this primitive is how many bytes it takes to reference any location in memory. For example, on a 32 bit target, this is 4 bytes and on a 64 bit target, this is 8 bytes.

If you find yourself writing code like this:
if foo >= bar {

let diff = unsafe { foo.unchecked_sub(bar) };
// ... use diff ...
}Consider changing it to
if let Some(diff) = foo.checked_sub(bar) {

Same value as self | other, but UB if any bit position is set in both inputs.
This is a situational micro-optimization for places where you’d rather use addition on some platforms and bitwise or on other platforms, based on exactly which instructions combine better with whatever else you’re doing. Note that there’s no reason to bother using this for places where it’s clear from the operations involved that they can’t overlap. For example, if you’re combining u16s into a u32 with((a as u32) << 16) | (b as u32), that’s fine, as the backend will know those sides of the | are disjoint without needing help.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.
This cannot overflow, as the double-width result has exactly enough space for the largest possible result. This is equivalent to how, in decimal, 9 × 9 + 9 + 9 = 81 + 18 = 99 = 9×10⁰ + 9×10¹ = 10² - 1.
