4///- Example
5///```

7///
8///ApiResponseErr::err(ApiErrors::to_rocketjson_error(error))

27///To forward Errors as [`ApiResponseErr`] [`rjtry`] can be used.
28///# Requirements
29///the trait [`ApiErrorsCreate`] has to be in scope.
30///# Example
31///```
32///use rocketjson::{ApiResponseErr, rjtry, error::ApiErrorsCreate};
33///
34///pub async fn db_get_users() -> Result<String, diesel::result::Error> {
35///    ...

40///    ApiResponseErr::ok(rocket::http::Status::Ok, user == "admin")
