/// Json helper
///
/// Json can be used for two different purpose. First is for json response
/// generation and second is for extracting typed information from request's
/// payload.
///
/// To extract typed information from request's body, the type `T` must
/// implement the `Deserialize` trait from *serde*.
///
/// [**JsonConfig**](dev/struct.JsonConfig.html) allows to configure extraction
/// process.
///
/// ## Example
///
/// ```rust,ignore
/// # extern crate actix_web;
/// #[macro_use] extern crate serde_derive;
/// use actix_web::{App, Json, Result, http};
///
/// #[derive(Deserialize)]
/// struct Info {
/// username: String,
/// }
///
/// /// deserialize `Info` from request's body
/// fn index(info: Json<Info>) -> Result<String> {
/// Ok(format!("Welcome {}!", info.username))
/// }
///
/// fn main() {
/// let app = App::new().resource(
/// "/index.html",
/// |r| r.method(http::Method::POST).with(index)); // <- use `with` extractor
/// }
/// ```
///
/// The `Json` type allows you to respond with well-formed JSON data: simply
/// return a value of type Json<T> where T is the type of a structure
/// to serialize into *JSON*. The type `T` must implement the `Serialize`
/// trait from *serde*.
///
/// ```rust,ignore
/// # extern crate actix_web;
/// # #[macro_use] extern crate serde_derive;
/// # use actix_web::*;
/// #
/// #[derive(Serialize)]
/// struct MyObj {
/// name: String,
/// }
///
/// fn index(req: HttpRequest) -> Result<Json<MyObj>> {
/// Ok(Json(MyObj {
/// name: req.match_info().query("name")?,
/// }))
/// }
/// # fn main() {}
