Changes

Beginning with this release, instead of putting all API-breaking changes into one group, now they are in the proper categories, but labeled as ⚠️ [API-breaking].

Main changes:

New deserialization API

The main change in this release is the deserialization API refactor. Its primary goal was to reduce overhead caused by all rows being eagerly deserialized to type-erased CqlValue type, only then being converted to end user types. Old traits and structs (FromCqlVal, FromRow, QueryResult - renamed to LegacyQueryResult, RowIterator - renamed to LegacyRowIterator, TypedRowIterator - renamed to LegacyTypedRowIterator) are replaced by new ones (DeserializeValue, DeserializeRow, new QueryResult, QueryPager, TypedRowStream). 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 increased efficiency - now, rows are deserialized straight to the end user type, without any copying and allocations on the way. Another feature is the ability to deserialize rows to borrowed types (e.g. &str or &[u8]). And the result metadata is now deserialized in the borrowed form, saving even more allocations.

The refactor included:

  • ⚠️ [API-breaking] Parametrized Deserialize{Value,Row} with two lifetimes: 'frame and 'metadata separately (#1101).
  • ⚠️ [API-breaking] The deserialization refactor was finished (#1088, #1107, #1109, #1093, #1057, #1120, #1118, #1122, #1121).
  • ⚠️ [API-breaking] Unified macro attributes' syntax and semantics between serialization and deserialization derive macros (#1119).

Other changes by category:

New features / enhancements:

  • ⚠️ [API-breaking] Made ResultMetadata lifetime-generic, which paved a path to deserializing metadata in a borrowed way as an optimisation to save allocations (#1082).
  • Exported serialization migration macros that accidentally hadn't been exported before (#1089).
  • Exposed public getters to type-erased errors (#1087).
  • Trace message is now issued upon successful keepalive (#1092).
  • Added SerializeRow impl for Box<T: SerializeRow> (#1105).
  • Exposed public getters for execution profile configuration (#1104).
  • Allowed public access to the profile associated with an execution profile handle (#1112).

Bug fixes:

  • ⚠️ [API-breaking] Fixed driver's logic that bases on error variants returned from query execution (#1075).
  • Fixed possible panic in speculative execution (#1086)
  • ⚠️ [API-breaking] Disallowed deserializing Counter type to plain i64 for type safety (#1106).
  • Fixed logic about ignoring particular error kinds if speculative execution failed (#1124).

API cleanups / better types:

  • ⚠️ [API-breaking] Some of our error types were restructured to be more strongly typed (instead of just containing a string) and better reflect the conditions that they appear in. This work will be continued in 0.16. (#1067, #1074, #1054, #1080, #1080, #1117).
  • Removed wildcard re-exports of the serialization framework's entities (#1090).
