Is there any way to handle ALL errors in a Rocket application?

[silvioprog]

Hi.

I would like to intercept all possible errors in a Rocket application, something like this:

impl<'r> Responder<'r> for ??? {
    fn respond_to(self, req: &Request) -> response::Result<'r> {
        status::Custom(Status::InternalServerError, self.to_string()).respond_to(req)
    }
}

So, is there any type to declare instead of ??? and intercept ANY error (from Serde, Diesel, std::io and so on) in the application?

Thank you!

Not currently, and I don't think we would add something so wide-reaching. Depending on what you want to do with it exactly, it may not even be possible in stable rust (see also #1232 (comment) RE: non_static_type_id). If you can provide more details on why you want a global error handler such as this I might be able to help more.

I am happy to revisit this with a compelling use-case, as requested by @jebrosen. Until then, I'm closing this out in favor of #1232.
