| ResultValue (R result) noexcept |
| Initializes result.
|
|
| ResultValue (R result, V &&value) noexcept |
| Initializes result.
|
|
const V & | getValue () const noexcept |
| Gets result value.
|
|
V && | takeValue () noexcept |
| Gets result value as rvalue.
|
|
const V * | operator-> () const noexcept |
| Gets result value.
|
|
| Result (R error) noexcept |
| Initializes result.
|
|
| Result () noexcept |
| Initializes result by default.
|
|
R | getError () const noexcept |
| Gets actual result value.
|
|
bool | isError () const noexcept |
| Checks for an error.
|
|
bool | isOk () const noexcept |
| Checks for a success.
|
|
| operator bool () const noexcept |
| Checks for a success.
|
|
| operator int () const noexcept=delete |
| Values of type bool participate in integral promotions. A prvalue of type bool can be converted to a prvalue of type int, with false becoming zero and true becoming one. This overload prevents the bool() operator above from participating in dangerous implicit conversion chains such as bool->int, bool->int->float, bool->int->double.
|
|
const char * | what () const noexcept |
| Gets a textual description of the result.

template<typename R, typename V>
struct fsdk::ResultValue< R, V, typename std::enable_if< std::is_copy_constructible< V >::value==false >::type >
Addon for Result to output some value aside the result. Specialization for non copiable types.
- Template Parameters
-
R | result enumeration type. |
V | result value type. |
- Note
- All rules for Result template parameter aplly to R.
-
V instance is always held by value despite -> operators.
