basic_result(A1 &&, A2 &&, Args ...)

Implicit inplace value or error constructor. Delegates to an appropriate explicit inplace constructor depending on input.

Requires: predicate::enable_inplace_value_error_constructor` is true.

Complexity: Same as for the value_type or error_type constructor which accepts A1, A2, Args .... Constexpr, triviality and noexcept of underlying operations is propagated.

Guarantees: If an exception is thrown during the operation, the state of the Args is left indeterminate.
