If the state associated with *this contains a deferred function, invoke
the deferred function. Otherwise, wait until the asynchronous result
associated with an instance of std::experimental::shared_future is ready.
void wait() const;
this->valid()
would return true.
Calls to get()
and wait()
from multiple threads on std::experimental::shared_future instances
that share the same associated state are serialized. If the associated
state contains a deferred function then the first call to get()
or wait()
invokes the deferred function and stores the returned value or
thrown exception as the asynchronous result.
Block until the asynchronous result associated with *this
is ready.
Nothing.
