mod.rs

1//! Vector compression for `OmenDB` storage
2//!
3//! Provides multiple compression methods:
4//! - Binary (BBQ): 32x compression, ~85% raw recall (~95% with rescore)
5//! - Scalar (SQ8): 4x compression, ~97% recall, 2-3x faster than FP32
6//! - RaBitQ: 8x compression, ~98% recall
7//! - FastScan: SIMD-accelerated batched distance computation (5x speedup)
