## What it is
RxDataSources is a Swift library providing reactive UITableView and UICollectionView data sources for RxSwift, with support for sectioned data, animated diff-based updates, and editing. It uses an O(N) diffing algorithm to compute minimal changesets for two-level hierarchical animations.

## Use cases
- bind observable data to a UITableView with RxSwift
- animate table view updates when items are inserted, deleted, or moved
- manage multi-section table or collection view data sources reactively
- diff two lists of items and apply minimal UI updates
- support row editing in a reactive table view

## When to choose
- you use RxSwift and need sectioned, animated table or collection view data binding
- you want automatic diffing with minimal batch updates instead of full reloads
- you need editing and two-level section/item animations out of the box

## When to avoid
- your project does not use RxSwift or reactive programming
- you use SwiftUI or Combine instead of UIKit with RxSwift
- your data contains duplicate items that break the uniqueness assumption for diffing
