#![recursion_limit = "512"] //! Actix-web codegen module //! //! Generators for routes and scopes //! //! ## Route //! //! Macros: //! //! - [get](attr.get.html) //! - [post](attr.post.html) //! - [put](attr.put.html) //! - [delete](attr.delete.html) //! - [head](attr.head.html) //! - [connect](attr.connect.html) //! - [options](attr.options.html) //! - [trace](attr.trace.html) //! - [patch](attr.patch.html) //! //! ### Attributes: //! //! - `"path"` - Raw literal string with path for which to register handle. Mandatory. //! - `guard="function_name"` - Registers function as guard using `actix_web::guard::fn_guard` //! - `wrap="Middleware"` - Registers a resource middleware. //! //! ## Notes //! //! Function name can be specified as any expression that is going to be accessible to the generate //! code (e.g `my_guard` or `my_module::my_guard`) //! //! ## Example: //! //! ```rust //! use actix_web::HttpResponse; //! use actix_web_codegen::get; //! //! #[get("/test")] //! async fn async_test() -> Result<HttpResponse, actix_web::Error> { //! Ok(HttpResponse::Ok().finish()) //! } //! ``` extern crate proc_macro; mod route; use proc_macro::TokenStream; /// Creates route handler with `GET` method guard. /// /// Syntax: `#[get("path"[, attributes])]` /// /// ## Attributes: /// /// - `"path"` - Raw literal string with path for which to register handler.
