The MongoDB Rust driver team is pleased to announce the v2.8.0 release of the mongodb crate, now available for download from crates.io.
Highlighted Changes
Search Index Management Helpers
The Collection type now has the create_search_index, create_search_indexes, update_search_index, drop_search_index, and list_search_indexes methods, allowing comprehensive management of search indexes from client code.
Reliability Improvements
More error types will be automatically retried, and retries will avoid mongos backends with network connectivity issues. Also note that the documentation for with_transaction has been updated to clarify error handling requirements to avoid a deadlock.
