v0.2.8

vectX v0.2.8

A maintenance release focused on code quality, removing dead code, and fixing all
compiler and Clippy warnings across the workspace.

What's Changed

Code quality

• Removed an unused deserialize_vector helper from the REST layer (the
  _optional variant covers all call sites).
• Annotated Qdrant API-compatibility request structs with #[allow(dead_code)]
  and clear comments so it's obvious which fields are accepted-for-compat-but-
  not-yet-routed (UpdateCollectionRequest, RecoverSnapshotRequest,
  CountRequest, SetPayloadRequest, DeletePayloadRequest,
  ClearPayloadRequest, DeleteVectorsRequest, BatchSearchRequest,
  SearchGroupsRequest, DiscoverRequest, ContextPair,
  DiscoverBatchRequest, FacetRequest, BatchQueryRequest,
  QueryGroupsRequest, VectorConfig).
• Cleaned up dead code in the storage manager and snapshot importer.
• Suppressed dead-method warnings on intentionally-retained HnswIndex
  helpers (contains, distance).
• Removed an unused HashMap import from the integration test.

Clippy fixes (workspace-wide)

• vectx-core: removed an unnecessary Distance::clone() (it's Copy) and
  switched two manual ceiling-division sites to usize::div_ceil.
• vectx-storage: dropped an empty if branch and replaced two
  Option::map(..).flatten() calls with Option::and_then.
• vectx-api: replaced while let Some(_) = iter.next() with for _ in iter,
  collapsed a nested if let / else if, and used Option::map where
  appropriate.

Examples

• Updated examples/data-chatbot/next-env.d.ts for the Next.js 16 typed-routes
  layout (./.next/dev/types/routes.d.ts).

Compatibility

No public API or wire-format changes. This is a drop-in replacement for v0.2.7.

Performance

Protocol	vs Qdrant	vs Redis
Insert (gRPC)	4.5x faster	10x faster
Search (gRPC)	6.3x faster	5x faster
