Function std::intrinsics::unchecked_sub

pub const 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)

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

返回未经检查的减法的结果，当 x - y > T::MAX 或 x - y < T::MIN 时导致未定义的行为。

此内联函数没有稳定的对应对象。
