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)

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.
