## What it is
Dodrio is a fast, bump-allocated virtual DOM library for Rust compiled to WebAssembly, using bumpalo arenas and a change-list stack machine for efficient DOM diffing. It is explicitly experimental and has not been updated since 2021.

## Use cases
- render ui in rust via webassembly
- virtual dom diffing in wasm
- build browser apps with rust instead of javascript
- fast dom updates using bump allocation
- implement todomvc or counter components in rust

## When to choose
- you want a minimal virtual DOM library (not a framework) for Rust/Wasm experiments
- you're researching bump-allocation-based rendering techniques
- you need fine-grained control over rendering without a full framework

## When to avoid
- you need a production-ready, maintained frontend solution
- you want a full framework with state management and routing
- you're not comfortable with an experimental library that likely has bugs

## Facets
- artifact type: library
- maturity: abandoned
- function: frontend-framework, ui-components, wasm
- domain: web-development, frontend, developer-tools
- platform: rust, wasm, browser
- tags: virtual-dom, bump-allocation, wasm-bindgen, rendering, rust
