core::intrinsics::unchecked_div

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

Unstable (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

Performs an unchecked division, resulting in undefined behavior where y = 0 or x = T::min_value() and y = -1
