How to handle Json Rejection

[sakinahwardanidanis]

Summary

Hey i am currently learning axum, and i just want to know: is it good to handle JSON rejection like this? or is there better way to do it?

#[derive(Serialize)]
struct Response {
    message: String,
}

#[derive(Deserialize)]
struct Request {
    message: String,
}

async fn post_request(body: Result<Json<Request>, JsonRejection>) -> impl IntoResponse {
    body.map_or_else(
        |_| {
            (
                axum::http::StatusCode::BAD_REQUEST,
                Json(Response {
                    message: String::from("Request tidak valid"),
                }),
            )
        },
        |json| {
            (
                axum::http::StatusCode::OK,
                Json(Response {
                    message: json.message.to_string(),
                }),
            )
        },
    )
}

If you have many errors that should produce a custom error when JSON deserialization fails, have a look at the customize-extractor-error example for ways to do that with less boilerplate.
