## What it is
Iron is an extensible, concurrency-focused web framework for Rust built on top of hyper. It provides a minimal core with middleware, plugins, and modifiers for extending request/response handling.

## Use cases
- build an http server in rust
- create a rest api with middleware
- handle concurrent web requests in rust
- build a web backend with a pluggable middleware chain
- serve  endpoints in rust

## When to choose
- you want a minimal, extensible middleware-based rust web framework
- you need 100% safe concurrent rust code for http handling
- you are maintaining an existing iron-based codebase

## When to avoid
- starting a new rust web project - actix-web, axum, or rocket are more actively maintained
- you need modern async/await ecosystem support
- you need frequent updates and security patches

## Facets
- artifact type: framework
- maturity: maintenance
- function: web-framework, http-server, middleware, routing
- domain: web-development, backend, developer-tools
- platform: rust, cross-platform
- tags: hyper-based, middleware-chain, extensible, concurrent, safe-code
