Error handling example
flosse opened this issue · comments
It would be great to have an example with proper error handling.
E.g. how can I use a custom AppError
within my routes? I'd like to write something like
fn post_foo<'a>(req: &mut nickel::Request<Data>,
res: nickel::Response<'a,Data>)
-> MiddlewareResult<'a,Data> {
let db = res.server_data().db.clone();
let foo = try!(something(&pool));
let bar = try!(precedure(&foo));
try!(baz(bar))
}
Each of the methods return a AppError
and somewhere central would be a custom mapping of the HTTP status codes and error messages. How can I achieve this?
In #304 I started with an example that needs to be improved. Could you help me?
