pub unsafe extern "rust-intrinsic" fn wrapping_sub<T: Copy>(a: T, b: T) -> T
🔬 This is a nightly-only experimental API. (
intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
Returns (a - b) mod 2N, where N is the width of T in bits.
The stabilized versions of this intrinsic are available on the integer
primitives via the
wrapping_sub method. For example,
