## What it is
Ergonomic Rust bindings for the Cloudflare Workers runtime, letting developers write entire Workers in Rust compiled to WebAssembly. It provides macros, request/response types, and integration with standard http crate types and frameworks like axum.

## Use cases
- write cloudflare workers in rust
- build serverless edge functions with rust
- compile rust to webassembly for cloudflare
- handle http requests in a worker via wasm
- deploy rust code to cloudflare edge with wrangler

## When to choose
- you want to write Cloudflare Workers in Rust instead of JavaScript
- you need strong typing and performance at the edge
- you want to reuse existing Rust crates in a serverless worker

## When to avoid
- you prefer JavaScript/TypeScript for Workers development
- you need a runtime other than Cloudflare Workers
- your dependencies cannot compile to wasm32-unknown-unknown

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, http-server, wasm, sdk
- domain: web-development, developer-tools, cloud-computing
- platform: rust, wasm, cloud, serverless
- tags: cloudflare-workers, serverless, webassembly, edge-computing, rust-bindings
