zvec-rust
zvec-rust is a Rust-native vector collection engine with a compiled Python API.
It provides durable storage (snapshot + write-ahead log), dense/sparse vector
search, scalar filtering, full-text search, and hybrid (multi-route) retrieval
with pluggable rerankers.
Install
pip install zvec-rust
Quick start
import zvec_rust as zvec
schema = zvec.CollectionSchema(
name="docs",
vectors=[zvec.VectorSchema("embedding", zvec.DataType.VECTOR_FP32, dimension=4)],
fields=[zvec.FieldSchema("category", zvec.DataType.STRING)],
)
col = zvec.create_and_open("./data/docs", schema, durability_mode="interval")
col.insert([
zvec.Doc("a", vectors={"embedding": [1.0, 0.0, 0.0, 0.0]}, fields={"category": "blog"}),
zvec.Doc("b", vectors={"embedding": [0.0, 1.0, 0.0, 0.0]}, fields={"category": "news"}),
])
# Vector search with a scalar filter.
hits = col.query(
zvec.Query(field_name="embedding", vector=[1.0, 0.0, 0.0, 0.0]),
topk=5,
filter="category == 'blog'",
)
# Hybrid (multi-route) search fused by a reranker.
hits = col.query(
[
zvec.Query(field_name="embedding", vector=[1.0, 0.0, 0.0, 0.0]),
zvec.Query(field_name="embedding", vector=[0.0, 1.0, 0.0, 0.0]),
],
topk=5,
reranker=zvec.RrfReRanker(),
)
Highlights
- Durability modes:
always,interval,manual(WAL + checkpoint + manifest). - Crash-recovery: committed ops are replayed from the WAL on reopen.
- ANN index params: HNSW, IVF, Flat, DiskANN, Vamana, HNSW-RaBitQ.
- Hybrid retrieval:
RrfReRanker,WeightedReRanker,CallbackReRanker. - Non-throwing
*_statusAPI surface returningStatusobjects.
See the project repository for the full API reference, production guide, and parity audit.
