Kinrany opened a new issue, #545:
URL: https://github.com/apache/arrow-rs-object-store/issues/545
**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
`Path` is central to `object_store`, but manipulating values of this type
can be hard because its API is mostly structured around one-way parsing.
**Describe the solution you'd like**
Expand `Path`s API. In no particular order:
- `fn empty()` constructor, equivalent to `Path::from("/")`
- `fn is_empty(&self) -> bool`, true if `self.raw` is empty
- `fn len(&self) -> usize`, equivalent to `.parts().count()`
- `fn prefix(&self) -> Self`, dual to the existing `Parts::filename`
- Bikeshedding: `fn folder`?
- Change `parts` to return a custom iterator that is fused and double-ended.
**Describe alternatives you've considered**
One could argue that `Path` is not designed to be used as a standalone type.
But then I would expect it to be internal to `object_store`, with all APIs
using `String` instead.
