Promise() [1/4]

template<typename V , typename E >

yaclib::Promise< V, E >::Promise ( const Promise< V, E > &  other )

yaclib::Promise< V, E >::Promise ( )

defaultnoexcept

The default constructor creates not a Valid Promise.

Needed only for usability, e.g. instead of std::optional<Promise<T>> in containers.
