std::jthread::operator= - std::jthread::operator=
std::jthread& operator=( std::jthread&& other )
noexcept; (since C++20)
If *this still has an associated running thread (i.e. joinable() == true),
calls
request_stop() followed by join(). Assigns the state of other to *this and
sets
other to a default constructed state.
After this call, this->get_id() is equal to the value of other.get_id()
prior to the
call and the associated stop-state is also moved, and other no longer
represents a
thread of execution nor has any stop-state.
other - another jthread object to assign to this jthread
object
