CollectiveAsync<E, C extends Collective<E>> class

An asynchronous wrapper for Collective operations that provides Future-based APIs.

This class implements both Collective and Iterable interfaces while converting all mutating operations into asynchronous operations that return Future objects. This enables non-blocking usage of collective operations.

Usage

final list = CollectiveList<int>.of([1, 2, 3]);
final asyncList = list.async; // Get async wrapper

await asyncList.add(4); // Asynchronous add
await asyncList.remove(2); // Asynchronous remove

Features

  • All mutating operations return Future<void> or Future<bool>
  • Maintains same interface as synchronous Collective
  • Preserves reactive behavior of the underlying collective
  • Thread-safe operations through Future-based API
