Struct Json 

pub struct Json<T>(pub T);

The JSON request body, deserialised.

#[derive(serde::Deserialize)]
struct NewPost { title: String }

let request = Arc::new(
    Request::builder().json(&serde_json::json!({ "title": "Hello" })).build(),
);
let Json(post) = Json::<NewPost>::from_request(request).await.unwrap();
assert_eq!(post.title, "Hello");
