Struct BundleCompression 

pub struct BundleCompression;

Bundle compression handler

This struct provides methods for handling compressed bundle data, including block info decompression and data block processing.

Implementations

impl BundleCompression

pub fn decompress_blocks_info( header: &BundleHeader, compressed_data: &[u8], ) -> Result<Vec<u8>, BinaryError>

Decompress blocks info data

This method handles the decompression of the blocks information section of a bundle, which contains metadata about all compression blocks.

pub fn decompress_blocks_info_limited( header: &BundleHeader, compressed_data: &[u8], max_uncompressed_size: Option<usize>, ) -> Result<Vec<u8>, BinaryError>

pub fn parse_compression_blocks( data: &[u8], ) -> Result<Vec<CompressionBlock>, BinaryError>

Parse compression blocks from decompressed blocks info

This method parses the compression block metadata from the decompressed blocks info data.

pub fn parse_compression_blocks_limited( data: &[u8], options: &BundleLoadOptions, ) -> Result<Vec<CompressionBlock>, BinaryError>

pub fn decompress_data_blocks( header: &BundleHeader, blocks: &[CompressionBlock], reader: &mut BinaryReader<'_>, ) -> Result<Vec<u8>, BinaryError>

Decompress all data blocks

This method reads and decompresses all data blocks from the bundle, returning the complete decompressed data.

pub fn decompress_data_blocks_limited( header: &BundleHeader, blocks: &[CompressionBlock], reader: &mut BinaryReader<'_>, max_memory: Option<usize>, ) -> Result<Vec<u8>, BinaryError>

pub fn get_compression_stats(blocks: &[CompressionBlock]) -> CompressionStats

Get compression statistics for blocks

pub fn validate_blocks(blocks: &[CompressionBlock]) -> Result<(), BinaryError>

Validate compression blocks

pub fn estimate_memory_usage(blocks: &[CompressionBlock]) -> usize

Estimate memory usage for decompression

pub fn is_compression_supported(compression_type: u32) -> bool

Check if compression type is supported
