Abstract Value Members

  1. abstract def continuous: Stream[F, A]

    Returns the continuous version of this signal, which emits the current A value on each request for an element from the stream.

    Returns the continuous version of this signal, which emits the current A value on each request for an element from the stream.

    Note that this may not see all changes of A as it always gets the current A at each request for an element.

  2. abstract def discrete: Stream[F, A]

    Returns the discrete version of this signal, updated only when the value is changed.

    Returns the discrete version of this signal, updated only when the value is changed.

    The value _may_ change several times between reads, but it is guaranteed the latest value will be emitted after a series of changes.

    If you want to be notified about every single change, use async.queue for signalling.

  3. abstract def get: F[A]

    Asynchronously gets the current value of this Signal.
