Creating new worktree for a local repository?

[NobodyXu]

Is it possible to create a new worktree for a local repository?
I'd like to use it as an optimization in cargo-binstall.

There is indeed a Worktree but I'm not sure whether it supports this functionality.

The Worktree doesn't have any capability to mutate itself yet, nor is there a way to create an official worktree like git worktree add does. However, creating worktree checkouts is relatively straightforward with gix::worktree::state::checkout(). Further, you could create a worktree_stream which allows to examine the whole worktree (as it would be checked out) in memory in a streaming fashion.

Since cargo-binstall controls these directories, getting a plain checkout should be enough.

Thank you!

Just a small question, can I simply pass |_oid, data| BlobRef { data: &*data } to parameter find?

[Byron]

I recommend to find references of the function in question - it should bring up multiple uses which can serve as example. Then it's something like { repo.objects.find_blob(oid, buf) }.
