I am looking into using Gitoxide as a library to download the file tree at a given commit (or branch) from a remote repository.

Is this use-case already supported? Is there an example somewhere?

Thanks for your interest. I think doing that is possible, even though I have not done that before.

Here is the rough steps that I anticipate.

start cloning a pack from the remote, but declare it as shallow with a depth of one to receive only a single commit along with all objects associated with it.
- possibly use an object filter to not download blobs
once the pack is written to disk and the index is generated, you can use the git-odb crate to access the objects within, which includes breadth-first tree traversal in the git-traverse crate.

I hope that helps.
