wait()

template<class T>

kj::Promise< void > nix::Sync< T, AsyncMutex >::Lock::wait ( )

inline

Releases the lock, waits for another promise to call Sync::notify, and reacquires the lock. There is no condition_variable-equivalent object to allow multiple wait queues on the same lock since we don't need that yet. There's no reason not to add such a type when needed.

wait_for()

std::cv_status nix::Sync< T, AsyncMutex >::Lock::wait_for ( std::condition_variable & cv, const std::chrono::duration< Rep, Period > & duration )

inline

Wait for the given condition variable for a maximum elapsed time of duration.

May spuriously wake up.

wait_until()

std::cv_status nix::Sync< T, AsyncMutex >::Lock::wait_until ( std::condition_variable & cv, const std::chrono::time_point< Clock, Duration > & duration )

inline

Wait for the given condition variable or until the time point duration.
