churust 0.1.1

//! # Churust 🌀
//!
//! A Ktor-inspired, secure, easy-to-learn web framework for Rust
//! (**Churro + Rust**).
//!
//! Churust gives you Ktor's developer experience on a battle-tested async stack
//! (tokio + hyper + rustls): an application engine, a routing DSL, an
//! `install(plugin)` system, a phased interceptor pipeline, hybrid handlers
//! (call-style *and* typed extractors), typed app state, layered configuration,
//! and secure-by-default behavior (body limits, request timeouts, panic
//! isolation, opt-in TLS).
//!
//! This is the umbrella crate: depend on it and enable plugins via Cargo
//! features. Core types come from [`churust_core`] (re-exported here); the
//! `#[churust::main]` attribute comes from `churust-macros`.
//!
//! ## Quick start
//!
//! ```no_run
//! use churust::prelude::*;
//!
//! #[churust::main]
//! async fn main() -> std::io::Result<()> {
//!     Churust::server()
//!         .routing(|r| {
//!             r.get("/", |_call: Call| async { "Hello from Churust 🌀" });
//!             r.get("/users/{id}", |Path(id): Path<u64>| async move {
//!                 format!("user #{id}")
//!             });
//!         })
//!         .start()
//!         .await
//! }
//! ```
//!
//! ## Testing without a socket
//!
//! Any app can be driven in-process with [`TestClient`] — no port binding, so
//! tests are fast and deterministic:
//!
//! ```
//! use churust::prelude::*;
//! use churust::TestClient;
//!
//! # tokio::runtime::Runtime::new().unwrap().block_on(async {
//! let app = Churust::server()
//!     .routing(|r| {
//!         r.get("/ping", |_c: Call| async { "pong" });
//!     })
//!     .build();
//!
//! let res = TestClient::new(app).get("/ping").send().await;
//! assert_eq!(res.status(), StatusCode::OK);
//! assert_eq!(res.text(), "pong");
//! # });
//! ```
//!
//! ## Feature flags
//!
//! Plugins live behind Cargo features (all off by default):
//!
//! | Feature   | Enables                                              |
//! |-----------|------------------------------------------------------|
//! | `json`    | `churust_json` — `Json<T>` + `ContentNegotiation`    |
//! | `logging` | `churust_logging` — `CallLogging`                    |
//! | `cors`    | `churust_cors` — `Cors`                              |
//! | `auth`    | `churust_auth` — `Auth` + `Principal<P>`             |
//! | `tls`     | rustls TLS support in [`churust_core`]               |
//! | `full`    | all four plugins                                     |
//!
//! ```toml
//! [dependencies]
//! churust = { version = "0.1", features = ["full"] }
//! tokio = { version = "1", features = ["full"] }
//! ```
//!
//! Bring the common items into scope with [`prelude`].
//!
//! ## The `#[churust::main]` attribute
//!
//! Builds a multi-threaded tokio runtime and blocks on the async body — the
//! Churust equivalent of `#[tokio::main]`:
//!
//! ```no_run
//! #[churust::main]
//! async fn main() -> std::io::Result<()> {
//!     use churust::prelude::*;
//!     let _app = Churust::server().build();
//!     Ok(())
//! }
//! ```
