explicit basic_result(in_place_type_t<error_type_if_enabled>, std::initializer_list<U>, Args …) - Boost.Outcome documentation

# `explicit basic_result(in_place_type_t<error_type_if_enabled>, std::initializer_list<U>, Args ...)`

Explicit inplace error constructor. Calls `void hook_result_in_place_construction(T *, in_place_type_t<U>, Args &&...) noexcept` with `this`, `in_place_type<error_type>`, `std::initializer_list<U>` and `Args ...`.

Requires: `predicate::enable_inplace_error_constructor<std::initializer_list<U>, Args ...>` is true.

Complexity: Same as for the `error_type` constructor which accepts `std::initializer_list<U>, 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.
