intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
Gets an identifier which is globally unique to the specified type. This function will return the same value for a type regardless of whichever crate it is invoked in.
Note that, unlike most intrinsics, this is safe to call;
it does not require an
Therefore, implementations must not require the user to uphold
any safety invariants.
The stabilized version of this intrinsic is
