The ScyllaDB team is pleased to announce ScyllaDB Rust Driver 0.11.0,
an asynchronous CQL driver for Rust, optimized for Scylla, but also compatible with Apache Cassandra!

Some interesting statistics:

  • over 1,018k downloads on crates; We passed a milion downloads!
  • over 490 GitHub stars!

Notable changes

The main feature of this PR is refactor of serialization API. Old traits and structs (Value, ValueList, BatchValues - renamed to LegacyBatchValues, SerializedValues - renamed to LegacySerializedValues) are replaced by new ones (SerializeCql, SerializeRow, new BatchValues, new SerializedValues). There are wrappers and helper implementations provided, designed to aid in gradually migrating to new API - see the migration guide in the book for more information. Old traits and structs will be removed in one of future versions.

New serialization API has a benefit of type safety - now, if you use wrong type for a bind marker in a query, you will get an understandable error locally (without actually executing the query on the database) instead of cryptic deserialization error from Scylla, or worse - silent data corruption.

API cleanups / breaking changes:

  • Improved support of common time and date crates - thanks Anfid for contribution (745)

New features / enhancements:

  • Check count of batch statements locally and reject too long batches without contacting the server. This PR also changes some improper usages of i16 to u16 (#824)
  • Implement Default for MaybeUnset (#883)

Documentation:

  • Updated Sphinx theme to 1.6 (#827)
  • Removed usage of illegal consistency level in an example (#840)
  • Removed redundant explicit link target in documentation (#848)
  • Updated UDT example to be in line with docs (#849)
  • Fixed a lot of typos (#876)

Bug fixes:

  • Manually dereference Option<&&str> in one place to work around possible rustc bug (#838)

CI / developer tool improvements:

  • Set workspace cargo resolver to version = 2 in order to get rid of annoying warning (#833)
  • Improved error handling in test_coalescing (#834)
  • Fix benchmarks compilation and compile them in CI to prevent further errors (#853)
  • Use latest Cassandra version again, as the new version fixed the problem that made our tests fail (#850)
  • Fix clippy new warning needless_borrows_for_generic_args (#861)
  • Added possibility to filter out control connection messages to the proxy (#863)
  • Commited renamed Cargo.lock file to be used in MSRV testing (#856)
  • Compile benchmarks when calling make ci so that developers can notice errors while testing locally (#877)
  • Pass the hostname of the container when checking for its health with cqlsh to unblock CI (#873)
