+--- -## 🚀 Vision +## Vision -**RustAPI** brings the developer experience (DX) of modern frameworks like **FastAPI** to the **Rust** ecosystem. +RustAPI redefines **API development for the AI era**. -We believe that writing high-performance, type-safe web APIs in Rust shouldn't require fighting with complex trait bounds or massive boilerplate. RustAPI provides a polished, battery-included experience where: +We combine Rust's performance and safety with FastAPI's ergonomics. Write type-safe, production-ready APIs without fighting trait bounds. **MCP servers**, **LLM integrations**, or classic REST APIs — one framework for all. -* **API Design is First-Class**: Define your schema, and let the framework handle Validation and OpenAPI documentation automatically. -* **The Engine is Abstracted**: We rely on industry standards like `tokio`, `hyper`, and `matchit` internally, but we expose a stable, user-centric API. This means we can upgrade the engine without breaking your code. -* **Zero Boilerplate**: Extractors and macros do the heavy lifting. +```rust +use rustapi_rs::prelude::*; -## ✨ Features +#[rustapi::get("/hello/:name")] +async fn hello(Path(name): Path) -> Json { + Json(Message { greeting: format!("Hello, {name}!") }) +} + +#[rustapi::main] +async fn main() -> Result<()> { + RustApi::new().mount_route(hello_route()).docs("/docs").run("0.0.0.0:8080").await +} +``` -- **⚡ Fast & Async**: Built on top of `tokio` and `hyper` 1.0. -- **🛡️ Type-Safe**: Request/Response bodies are strictly typed using generic extractors (`Json`, `Query`, `Path`). -- **📝 Automatic OpenAPI**: Your code *is* your documentation. Swagger UI is served at `/docs` out of the box. -- **✅ Built-in Validation**: Add `#[validate(email)]` to your structs and get automatic 422 error handling. -- **🧩 Intuitive Routing**: Radix-tree based routing with simple macros `#[rustapi::get]`, `#[rustapi::post]`. -- **🔋 Batteries Included**: Middleware, JWT auth, CORS, rate limiting, and configuration management. -- **🔐 Security First**: JWT authentication, CORS middleware, and IP-based rate limiting out of the box. -- **⚙️ Configuration**: Environment-based config with `.env` file support and typed config extraction. +5 lines of code. Auto-generated OpenAPI docs.
