Utility methods to create StreamTransfomer instances to manipulate Streams.

asyncMapBuffer

Like asyncMap but events are buffered in a List until previous events have been processed rather than being called for each element individually.

asyncWhere

Like where but allows an asynchronous predicate.

audit

Audit waits for a period of time after receiving a value and then only emits the most recent value.

buffer

Collects values from a source stream until a trigger stream fires and the collected values are emitted.

debounce, debounceBuffer

Prevents a source stream from emitting too frequently by dropping or collecting values that occur within a given duration.

concurrentAsyncMap

Like asyncMap but the convert callback can be called with subsequent values before it has finished for previous values.

followedBy

Appends the values of a stream after another stream finishes.

merge, mergeAll

Interleaves events from multiple streams into a single stream.

scan

Scan is like fold, but instead of producing a single value it yields each intermediate accumulation.

startWith, startWithMany, startWithStream

Prepend a value, an iterable, or a stream to the beginning of another stream.

switchMap, switchLatest

Flatten a Stream of Streams into a Stream which forwards values from the most recent Stream

takeUntil

Let values through until a Future fires.

tap

Taps into a single-subscriber stream to react to values as they pass, without being a real subscriber.

throttle

Blocks events for a duration after an event is successfully emitted.
