Function core::intrinsics::ptr_guaranteed_cmp
const: unstable · source · pub extern "rust-intrinsic" fn ptr_guaranteed_cmp<T>(
ptr: *const T,
other: *const T
) -> u8🔬This is a nightly-only experimental API. (
core_intrinsics)Expand description
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.
