Function std::intrinsics::ptr_guaranteed_cmp

pub extern "rust-intrinsic" fn ptr_guaranteed_cmp<T>(
    ptr: *const T,
    other: *const T
) -> u8

See documentation of <*const T>::guaranteed_eq for details. Returns 2 if the result is unknown. Returns 1 if the pointers are guaranteed equal Returns 0 if the pointers are guaranteed inequal

Note that, unlike most intrinsics, this is safe to call; it does not require an unsafe block. Therefore, implementations must not require the user to uphold any safety invariants.
