-/**
- * This is an optional value type. It holds a `Result` and, if that code is ResultSuccess, it
- * also holds a result of type `T`. If the code is an error code (not ResultSuccess), then trying
- * to access the inner value with operator* is undefined behavior and will assert with Unwrap().
- * Users of this class must be cognizant to check the status of the ResultVal with operator bool(),
- * Code(), Succeeded() or Failed() prior to accessing the inner value.
- *
- * An example of how it could be used:
- * \code
- * ResultVal<int> Frobnicate(float strength) {
- *     if (strength < 0.f || strength > 1.0f) {
- *         // Can't frobnicate too weakly or too strongly
- *         return Result{ErrorModule::Common, 1};
- *     } else {
- *         // Frobnicated! Give caller a cookie
- *         return 42;
- *     }
- * }
- * \endcode
- *
- * \code
- * auto frob_result = Frobnicate(0.75f);
- * if (frob_result) {
- *     // Frobbed ok
- *     printf("My cookie is %d\n", *frob_result);
- * } else {
- *     printf("Guess I overdid it. :( Error code: %ux\n", frob_result.Code().raw);
- * }
- * \endcode
