Keywords: rust, rustlang, rust-lang, unchecked_sub

# [−][src]Function std::intrinsics::unchecked_sub

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

🔬 This is a nightly-only experimental API. (`core_intrinsics` #0)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Returns the result of an unchecked substraction, resulting in undefined behavior when `x - y > T::max_value()` or `x - y < T::min_value()`.
