-# The "nullable pointer optimization"
-
-Certain types are defined to not be `null`. This includes references (`&T`,
-`&mut T`), owning pointers (`~T`), and function pointers (`extern "abi"
-fn()`). When interfacing with C, pointers that might be null are often used.
-As a special case, a generic `enum` that contains exactly two variants, one of
-which contains no data and the other containing a single field, is eligible
-for the "nullable pointer optimization". When such an enum is instantiated
-with one of the non-nullable types, it is represented as a single pointer,
-and the non-data variant is represented as the null pointer. So
-`Option<extern "C" fn(c_int) -> c_int>` is how one represents a nullable
-function pointer using the C ABI.
