## What it is
An Android library providing a single RecyclerView adapter that supports multiple view types, reusable renderers, nested RecyclerViews, DiffUtil, and view state saving. It eliminates the need to write boilerplate adapters for each list in an Android project.

## Use cases
- display lists with multiple item view types in one RecyclerView
- avoid writing a new adapter for every RecyclerView
- add nested horizontal RecyclerViews inside list items
- efficiently update lists with DiffUtil and payloads
- save and restore item view state while scrolling
- add load-more indicators to endless lists
- bind views without ViewHolders using ViewBinder

## When to avoid
- you use Jetpack Compose instead of the View/RecyclerView system
- your project targets Android below API 21
- you need a maintained, actively developed solution with modern Kotlin-first APIs
