How to implement my custom responder

[un4gt]

Here is my custom response:

#[derive(Serialize)]
pub struct ApiResponse<T> {
    code: u16,
    message: String,
    detail: Option<T>
}

And there is my implemention:

impl<T: Serialize> Responder for ApiResponse<T> {
    type Body = BoxBody;

    fn respond_to(self, _: &HttpRequest) -> HttpResponse<Self::Body> {
        let body = serde_json::to_string(&self).unwrap();
        HttpResponse::Ok()
            .content_type("application/json")
            .body(body)
    }
}

It works, but i don't know that is the true way. It should include sth like future ?

Looks good. Response is not an async trait, but it's body types are allowed to be Streams.

Thanks, I'll try to learn more about Stream.
