Expand description

Computes `a + b`, saturating at numeric bounds.

Note that, unlike most intrinsics, this is safe to call; it does not require an `unsafe` block. Therefore, implementations must not require the user to uphold any safety invariants.

The stabilized versions of this intrinsic are available on the integer primitives via the `saturating_add` method. For example, `u32::saturating_add`
