Crate uni_sparse_vector 

Learned-sparse (SPLADE / BGE-M3) vector type for the Uni graph database.

A leaf crate with zero uni-* dependencies — the same layering as uni-btic. It owns the SparseVector type, its validating constructor, the lossless binary encode codec, the pure scoring kernels in ops (notably ops::sparse_dot), and SparseError. All glue — Value/DataType variants, Arrow lowering, CV tag framing, DDL, the index — lives in the integration crates that depend on this one.

Modules

encode

error

ops

Pure scoring/transform kernels over SparseVector. No graph/runtime dependencies — this is the analogue of uni-btic’s interval math, kept in the type crate so every layer (index, rerank, brute-force oracle) calls one canonical implementation.
