oxc_allocator crate is currently undergoing a lot of changes. We are in the process of replacing Vec with our own custom implementation (#9646 and later PRs). We also intend to replace bumpalo with our own allocator soon. So it's not an ideal time to be making this kind of change.

Out of interest, can you please outline what your use case is that requires no_std?

This pr could be postponed when refactor is done:)

I'm hesitant to maintain no_std.

And I also couldn’t find any public repositories from you that rely on Oxc.

Please reach out / provide more context if this is for a company project.

I think oxc_allocator itself doesn't take much effort to be maintained as no_std (no multithread code now), and making it no_std will allow more users to use it.

It is personal experimental project currently, may contribute to naga in wgpu in future.
