## Summary We often match on `ErrorKind` to figure out how to handle an error (e.g., to treat a 404 as "Not found" rather than aborting the program). Unfortunately, if we retry, we wrap the error in a new kind that includes the retry count. This PR adds an unwrapping mechanism to ensure that callers always look at the underlying error.
