Struct Json

Source

pub struct Json<T>(pub T);

Expand description

JSON body extractor

Parses the request body as JSON and deserializes into type T. Also works as a response type when T: Serialize.

§Example

#[derive(Deserialize)]
struct CreateUser {
    name: String,
    email: String,
}

async fn create_user(Json(body): Json<CreateUser>) -> impl IntoResponse {
    // body is already deserialized
}
