carlsverre opened a new issue, #579:
URL: https://github.com/apache/arrow-rs-object-store/issues/579
**Describe the bug**
If an `HttpError` occurs in a retry context, the error is mapped into a
`retry::RequestError`, which is not public to this crate. However, when you try
to retrieve the underlying `HttpError` via recursively calling `source`, you
instead receive the lower-level `reqwest::Error`. This makes handling HttpError
types consistently difficult for consumers who may not want to know about
`reqwest`.
**To Reproduce**
Receive an HttpError in a retry context. Attempt to retrieve the underlying
HttpError using something like:
```rust
let mut err: &dyn Error = &e;
let mut found = false;
while let Some(source) = err.source() {
err = source;
if let Some(err) = err.downcast_ref::<HttpError>() {
found = true;
assert_eq!(err.kind(), HttpErrorKind::Request);
}
}
assert!(found, "HttpError not found in source chain");
```
**Expected behavior**
I get an HttpError
