How can I implement a single commit handler when writing to a dataset using both Rust and Python simultaneously?

My application scenario involves writing datasets using Python and Rust. I implemented an External Manifest Store in Rust, which provides atomic transaction commits. However, this solution cannot be used with Python, and the commit handler has requirements for the writers, specifically that only one commit handler can be active at a time.Are there any solutions to this problem?

Review the Rust External Manifest Store and the Python dataset-writing path, focusing on how commit handlers are created and enforced for writers. Determine whether the existing interfaces expose a shared cross-language transaction mechanism. Done means identifying and documenting a supported way for Rust and Python writers to coordinate a single active commit handler, or clearly recording the missing capability.
