Is there anyway to combine anyhow result with http response?

[DennisZhangOiler]

like

#[web::get]
async fn index() -> anyhow::Result<impl Responder>

I think the best way is to create your own type and convert the anyhow::Error into your custom type

Something like this:

#[derive(Clone, Debug, Serialize, Deserialize)]
pub struct HttpError {
  #[serde(skip)]
  pub status: http::StatusCode,
  pub msg: String,
}

/// Implement standard error for HttpError
impl std::error::Error for HttpError {}

/// Helper function to convert an HttpError into a ntex::web::HttpResponse
impl web::WebResponseError for HttpError {
  fn error_response(&self, _: &web::HttpRequest) -> web::HttpResponse {
    web::HttpResponse::build(self.status).json(&self)
  }
}

impl From<anyhow::Error> for HttpError {
  fn from(err: anyhow::Error) -> Self {
    HttpError {
      status: http::StatusCode::BAD_REQUEST,
      msg: err.to_string(),
    }
  }
}

I was looking for some wrapper automatically does it, but eventually I did it this way.

it is possible to override all errors in ntex. I just updated error handling example
