Result Class
template <typename T = void> class Utils::ResultResult<T> is used for returning either a success value or an error string from a function. More...
| Header: | #include <Result> |
Detailed Description
The Result typedef is a shorthand for expected<T, QString>, with the expected value of type T being returned in the success case, and the unexpected value being an error message for the user.
Use Result<> as the type when you do not have a concrete success value to return (do not use Result<bool>). In that case, return Utils::ResultOk to return success. You can also use the convenience function Utils::makeResult to combine the success and error cases.
Return a Utils::ResultError value as a convenience class for the error case.
See also Utils::ResultOk, Utils::ResultError, and Utils::makeResult.
