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

# `explicit basic_outcome(in_place_type_t<value_type_if_enabled>, std::initializer_list<U>, Args ...)`

Explicit inplace value constructor. Calls `void hook_outcome_in_place_construction(T *, in_place_type_t<U>, Args &&...) noexcept` with `this`, `in_place_type<value_type>`, ‘std::initializer_list’ and `Args ...`.

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

Complexity: Same as for the `value_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.
