Struct Compressor 

pub struct Compressor { /* private fields */ }

Compressor for LANCE payloads

NOTE: Full implementation requires lz4 and zstd crate dependencies. This provides the API structure and header format.

Implementations

impl Compressor

pub fn new(algorithm: CompressionAlgorithm, _level: i32) -> Self

Create a new compressor with the specified algorithm

pub fn lz4() -> Self

Create an LZ4 compressor (fast, moderate compression)

pub fn zstd(_level: i32) -> Self

Create a ZSTD compressor - requires zstd feature

pub fn with_max_size(self, max_size: usize) -> Self

Set the maximum allowed decompressed size

pub fn algorithm(&self) -> CompressionAlgorithm

Get the compression algorithm

pub fn compress(&self, data: &[u8]) -> CompressionResult<Bytes>

Compress data and prepend compression header

pub fn decompress(&self, data: &[u8]) -> CompressionResult<Bytes>

Decompress data with header

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

Raw compression without header.

pub fn decompress_raw( &self, algorithm: CompressionAlgorithm, data: &[u8], _original_size: usize, ) -> CompressionResult<Bytes>

Raw decompression without header.

pub fn should_compress(&self, data_len: usize) -> bool

Check if compression would be beneficial for this data size

Trait Implementations

impl Clone for Compressor

fn clone(&self) -> Compressor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Compressor

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

Formats the value using the given formatter.

impl Default for Compressor

fn default() -> Self

Returns the “default value” for a type.
