Getting started

How to install

Add actix-json-response to your dependencies:

```toml [dependencies]

...

actix-web = "4" actix-json-response = "0.1" ```

Quickstart

actix-json-response exposes the JsonResponse type which implements Actix's Responder trait. It is generic and receives a type parameter that must implement Serde's Serialize trait:

```rust,compilefail use actixweb::{get, web, Result}; use actixjsonresponse::JsonResponse; use serde::Serialize;

[derive(Serialize)]

struct MyObj { name: String, }

[get("/a/{name}")]

async fn index(name: web::Path) -> Result> { let myobj = MyObj { name: name.tostring(), }; Ok(my_obj.into()) }

[actix_web::main]

async fn main() -> std::io::Result<()> { use actix_web::{App, HttpServer};

HttpServer::new(|| App::new().service(index))
    .bind(("127.0.0.1", 8080))?
    .run()
    .await

} ```

By default, the response will have status code 200. If you need the response to have a status code other than 200, you can use the with_status_codemethod that receives an Actix's StatusCode:

``` use actix_web::http::StatusCode;

[get("/a/{name}")]

async fn index(name: web::Path) -> Result> { let myobj = MyObj { name: name.tostring(), }; Ok(JsonResponse::from(myobj).withstatus_code(StatusCode::CREATED)) // The response will have status code 201 in this case } ```
