   I've opened a PR to add serialization/deserialization support for the CAGRA Rust bindings: #1840

   This adds serialize(), serialize_to_hnswlib(), and deserialize() methods to cagra::Index, wrapping the existing C API functions that were not yet exposed in Rust. Includes round-trip tests and documentation.

   I've submitted a PR to address this: #1840

   The PR adds serialize() and deserialize() methods to the Rust CAGRA Index API, matching the existing functionality in the C/C++ API.

   This is critical for production use cases where:

   • CAGRA indexes need to persist across service restarts
   • Building a fresh index on startup is too slow (especially for large datasets)
   • High-availability deployments require pre-built indexes

   Happy to iterate on the implementation based on feedback!
