- <p>How to implement <a href="../../reference/types/in_place_type_t.html" class="api-reference"><code>in_place_type_t<T></code></a>
- and <code>in_place_type<T></code>.</p>
- <p>If set to <code>1</code>, the <code><utility></code> header is included, and <code>std::in_place_type_t<T></code>
- is aliased into <code>BOOST_OUTCOME_V2_NAMESPACE::in_place_type_t<T></code> along with
- <code>std::in_place_type<T></code>.</p>
- <p>If set to <code>0</code>, a local emulation is used.</p>
- <p><em>Overridable</em>: Define before inclusion.</p>
- <p><em>Default</em>: If the current compiler implements C++ 17 or later, if unset
- this macro is defaulted to <code>1</code>, otherwise it is defaulted to <code>0</code>.</p>
- <p><em>Header</em>: <code><boost/outcome/config.hpp></code></p>
