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

或 x - y < T::MIN
时导致未定义的行为。
