Function wrapping_sub

const fn wrapping_sub<T: Copy>(a: T, b: T) -> T

Returns (a - b) mod 2N, where N is the width of T in bits.

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 wrapping_sub method. For example, u32::wrapping_sub
