Function core::intrinsics::unchecked_sub

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

This is supported on non-crate feature miri-test-libstd or test or doctest only.

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.
