Why does req.Response have errors as member fields?

[adityathebe]

Hey, I've been learning quite a bit from this library.

I am curious to know why the Response object needs to have error fields (let alone 2 of them)? Why can't the errors be propagated as return values?

Cheers

errors are propagated as return value:

resp, err := client.R().Get(url)

And also record into Response.Err, it is useful in middleware, e.g. Handle Exceptions with Middleware
