Compression configuration

Fields

level: CompressionLevel

Compression level

Implementations

impl CompressionConfig

pub fn new() -> Self

Create new compression config

pub fn with_level(self, level: CompressionLevel) -> Self

Set compression level

pub fn with_delta_encoding(self, enabled: bool) -> Self

Enable/disable delta encoding

pub fn with_varint_encoding(self, enabled: bool) -> Self

Enable/disable varint encoding

pub fn with_bulk_compression(self, enabled: bool) -> Self

Enable/disable bulk compression

pub fn compress_ids(&self, ids: &[usize]) -> Result<Vec<u8>>

Compress a list of IDs (neighbor lists)

Uses delta + varint encoding for efficient compression of sequential IDs.

pub fn decompress_ids(&self, data: &[u8], count: usize) -> Result<Vec<usize>>

Decompress a list of IDs

pub fn compress_bulk(&self, data: &[u8]) -> Result<Vec<u8>>

Compress arbitrary binary data

pub fn decompress_bulk(&self, data: &[u8]) -> Result<Vec<u8>>

Decompress arbitrary binary data

pub fn compress_floats( &self, values: &[f32], precision_bits: u8, ) -> Result<Vec<u8>>

Compress floating-point values with quantization

Reduces precision to save space (e.g., float32 -> float16 or fixed-point)

pub fn decompress_floats( &self, data: &[u8], count: usize, precision_bits: u8, ) -> Result<Vec<f32>>

Decompress floating-point values

Trait Implementations

impl Clone for CompressionConfig

fn clone(&self) -> CompressionConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CompressionConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CompressionConfig

fn default() -> Self

Returns the “default value” for a type.
