Abstract Value Members

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

    Permalink

    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]

    Permalink

    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]

    Permalink

    Asynchronously gets the current value of this Signal.
