EventStream

See docs for DebounceEventStream

See also debug convenience method in BaseObservable

Make a stream that emits this stream's values but waits for after stream to emit first in a given transaction. You can use this for Signals too with Signal.composeChanges (see docs for more details)

See docs for MapEventStream

See docs for ThrottleEventStream

Return the observable's topoRank. This does not affect the observable in any way.

Create a new observable that listens to the original, and set the displayName of the new observable. This is different from setDisplayName.

If you say stream.debugWithName("foo").debugLog(), the displayName used by the logger will be "foo" verbatim, whereas if you say stream.setDisplayName("foo").debugLog(), the logger's displayName will be "foo|Debug" – with a suffix – to differentiate it from the "foo" displayName of stream itself.

This is the method that subclasses override to preserve the user's ability to set custom display names.

Create an external observer from a function and subscribe it to this observable.

Note: since you won't have a reference to the observer, you will need to call Subscription.kill() to unsubscribe

value is passed by name, so it will be evaluated whenever the Observable fires. Use it to sample mutable values (e.g. myInput.ref.value in Laminar).

See also: mapToStrict

value is evaluated strictly, only once, when this method is called.

Set the display name for this instance (observable or observer).

• This method modifies the instance and returns this. It does not create a new instance.
• New name you set will override the previous name, if any. This might change in the future. For the sake of sanity, don't call this more than once for the same instance.
• If display name is set, toString will output it instead of the standard type@hashcode string

Override defaultDisplayName instead of this, if you need to.

Convert this observable to a signal of Option[A]. If it is a stream, set initial value to None.
