Abstract Value Members

  1. abstract def awaitShutdown(implicit trace: Trace): UIO[Unit]

    Waits until the queue is shutdown.

    Waits until the queue is shutdown. The IO returned by this method will not resume until the queue has been shutdown. If the queue is already shutdown, the IO will resume right away.

  2. abstract def capacity: Int

    How many elements can hold in the queue

    How many elements can hold in the queue

  3. abstract def isShutdown(implicit trace: Trace): UIO[Boolean]

    true if shutdown has been called.

    true if shutdown has been called.

    Enqueue
  4. abstract def publish(a: A)(implicit trace: Trace): UIO[Boolean]

    Publishes a message to the hub, returning whether the message was published to the hub.

  5. abstract def publishAll[A1 <: A](as: Iterable[A1])(implicit trace: Trace): UIO[Chunk[A1]]

    Publishes all of the specified messages to the hub, returning any messages that were not published to the hub.

  6. abstract def shutdown(implicit trace: Trace): UIO[Unit]

    Interrupts any fibers that are suspended on offer or take.

    Interrupts any fibers that are suspended on offer or take. Future calls to offer* and take* will be interrupted immediately.

    Enqueue
  7. abstract def size(implicit trace: Trace): UIO[Int]

    Retrieves the size of the queue.

    Retrieves the size of the queue. This may be negative if fibers are suspended waiting for elements to be added to the queue or greater than the capacity if fibers are suspended waiting to add elements to the queue.

    Enqueue
  8. abstract def subscribe(implicit trace: Trace): ZIO[Scope, Nothing, Dequeue[A]]

    Subscribes to receive messages from the hub.

    Subscribes to receive messages from the hub. The resulting subscription can be evaluated multiple times within the scope to take a message from the hub each time.

  17. final def offerAll[A1 <: A](as: Iterable[A1])(implicit trace: Trace): UIO[Chunk[A1]]

    For Bounded Queue: uses the BackPressure Strategy, places the values in the queue and always returns no leftovers.

    For Bounded Queue: uses the BackPressure Strategy, places the values in the queue and always returns no leftovers. If the queue has reached capacity, then the fiber performing the offerAll will be suspended until there is room in the queue.

    For Unbounded Queue: Places all values in the queue and returns no leftovers.

    For Sliding Queue: uses Sliding Strategy If there is room in the queue, it places the values otherwise it removes the old elements and enqueues the new ones. Always returns no leftovers.

    For Dropping Queue: uses Dropping Strategy, It places the values in the queue but if there is no room it will not enqueue them and return the leftovers.
