Hi Burak,

I'm having hard times trying to merge the series in bitmap-for-next.

$ git am -3 v14_20250813_bqe_rust_adds_bitmap_api_id_pool_and_bindings.mbx
Applying: rust: add bindings for bitmap.h
Applying: rust: add bindings for bitops.h

Patch failed at 0003 rust: add bitmap API.
hint: Use 'git am --show-current-patch=diff' to see the failed patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

Can you please rebase and resend?

Thanks,
Yury
