ultrasync-index
Rust-backed mmapped index and vector search for ultrasync.
This package provides the low-level index primitives:
- GlobalIndex - memory-mapped file index with zero-copy access
- ThreadIndex - in-memory vector index for fast similarity search
- TreeSitter scanner - AST-based symbol extraction (optional)
- Candle embeddings - Rust-native embeddings via HuggingFace (optional)
Installation
pip install ultrasync-index
Or as part of the full ultrasync package:
pip install ultrasync
Usage
from ultrasync_index import GlobalIndex, ThreadIndex
# Memory-mapped global index
index = GlobalIndex("index.dat", "blob.dat")
data = index.slice_for_key(key_hash)
# In-memory thread-local index
thread_idx = ThreadIndex()
thread_idx.add(key_hash, embedding_vector)
results = thread_idx.search(query_vector, top_k=10)
Features
scanner- Tree-sitter based symbol extraction (enabled by default)embeddings- Candle-based Rust-native embeddings (enabled by default)mkl- Intel MKL acceleration for embeddingscuda- CUDA acceleration for embeddings
