Function unchecked_sub

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

🔬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.

The stable counterpart of this intrinsic is unchecked_sub on the various integer types, such as u16::unchecked_sub and i64::unchecked_sub.
