pub const unsafe extern "rust-intrinsic" fn unchecked_sub<T>(
x: T,
y: T,
) -> Twhere
T: Copy,🔬This is a nightly-only experimental API. (
core_intrinsics)Expand description
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.
