Function std::intrinsics::unchecked_div

pub const unsafe extern "rust-intrinsic" fn unchecked_div<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

执行未经检查的除法，从而导致 y == 0 或 x == T::MIN && y == -1 出现不确定的行为

可通过 checked_div 方法在整数基元上使用此内联函数的安全包装。 例如， u32::checked_div
