| 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.

## Detailed Description

### 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.

| inline noexcept

Initializes result.

Parameters

  [in] | result | value to set.

## ◆ ResultValue() [2/2]

template<typename R , typename V >
