🔬 This is a nightly-only experimental API.   (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Performs checked integer subtraction The stabilized versions of this intrinsic are available on the integer primitives via the overflowing_sub method. For example, std::u32::overflowing_sub
