Function std::intrinsics::unchecked_sub

pub unsafe extern "rust-intrinsic" fn unchecked_sub<T>(x: T, y: T) -> T where    T: Copy,

🔬 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

Returns the result of an unchecked subtraction, resulting in undefined behavior when x - y > T::MAX or x - y < T::MIN.

This intrinsic does not have a stable counterpart.
