Utility functions for storage operations

Implementations§

Source§

impl StorageUtils

Source

pub fn vectors_to_binary(vectors: &[Vector]) -> Result<Vec<u8>>

Convert vectors to binary format

Source

pub fn binary_to_vectors(data: &[u8], dimensions: usize) -> Result<Vec<Vector>>

Convert binary data to vectors

Source

pub fn estimate_storage_size( vector_count: usize, dimensions: usize, compression: CompressionType, ) -> usize

Rough heuristic storage-size estimate for capacity planning when no actual vector data is available yet (only counts/dimensions are known).

These ratios are empirical averages for typical dense f32 embedding data; they are NOT measured against vectors (there are none to measure here). For a real, measured ratio on actual data use StorageUtils::benchmark_compression, which drives the same compress_bytes codepath used by VectorWriter.

Source

pub fn benchmark_compression( vectors: &[Vector], ) -> Result<Vec<(CompressionType, f64, usize)>>

Benchmark compression algorithms by actually compressing vectors through the same compress_bytes codepath used by VectorWriter, so the reported sizes and timings reflect real OxiARC output.
