calavera opened a new issue, #469:
URL: https://github.com/apache/arrow-rs-object-store/issues/469
**Describe the bug**
<!--
A clear and concise description of what the bug is.
-->
If there is some kind of network error in idempotent requests, object-store
will try to retry. If retries don't succeed, object-store returns an
`Error::Generic`, which `source` is a `RetryError`.
It's impossible to downcast the `source` error into a `RetryError` because
the `RetryError` type is private.
**To Reproduce**
<!--
Steps to reproduce the behavior:
-->
This code does not compile because `RetryError` is not public:
```rust
match error {
Error::Generic { source, .. } if let Some(source) =
source.downcast_ref::<RetryError>() => source,
_ => error
```
**Expected behavior**
<!--
A clear and concise description of what you expected to happen.
-->
I'd expect to be able to access the data into the RetryError which
ultimately has information about the real problem that cause a request to fail.
**Additional context**
<!--
Add any other context about the problem here.
