The async package will contain tools to work with asynchronous computations.

The package contains sub-libraries with different utilities.

Zipping streams

The "stream_zip.dart" sub-library contains functionality to combine several streams of events into a single stream of tuples of events.

Results

The "result.dart" sub-library introduces a Result class that can hold either a value or an error. It allows capturing an asynchronous computation which can give either a value or an error, into an asynchronous computation that always gives a Result value, where errors can be treated as data. It also allows releasing the Result back into an asynchronous computation.

History.

This package is unrelated to the discontinued async package with version 0.1.7.
