finalfusion/finalfusion-rust

Supports multiple vocabulary and storage backends including memory-mapped and product-quantized embeddings for flexible performance/memory tradeoffs, plus cross-format conversion (fastText, word2vec, GloVe). Enables similarity and analogy queries through `ndarray`-backed vector operations, with optional BLAS/LAPACK acceleration for quantized lookups. Integrates with the finalfusion ecosystem for training embeddings via finalfrontier and quantization via the reductive crate.
