std::shared_future<T>::operator=: std::shared_future<T>::operator=

NAME

std::shared_future<T>::operator= - std::shared_future<T>::operator=

Synopsis

shared_future& operator=( const shared_future& other ); (since C++11)
                                                                 (1) (until C++17)
shared_future& operator=( const shared_future& other ) noexcept; (since C++17)
shared_future& operator=( shared_future&& other ) noexcept; (2) (since C++11)

Assigns the contents of another shared_future.
1) Releases any shared state and assigns the contents of other to *this. After the assignment, this->valid() == other.valid().
2) Releases any shared state and move-assigns the contents of other to *this. After the assignment, other.valid() == false and this->valid() will yield the same value as other.valid() before the assignment.

Parameters

other - a std::shared_future that will transfer state to *this

Return value

*this
