Struct DxCompressed 

pub struct DxCompressed { /* private fields */ }

Compressed DX-Machine buffer

Wraps compressed data with lazy decompression. The first access triggers decompression, subsequent accesses use cache.

Implementations

impl DxCompressed

pub fn new() -> Self

Create empty compressed buffer

pub fn compress(data: &[u8]) -> Self

Compress data using LZ4 (fast, pure Rust)

LZ4 provides good compression with excellent speed (pure Rust, no C dependencies).

pub fn compress_level(data: &[u8], _level: CompressionLevel) -> Self

Compress with level hint

pub fn compressed_size(&self) -> usize

Get compressed size

pub fn original_size(&self) -> usize

Get original (uncompressed) size

pub fn ratio(&self) -> f64

Get compression ratio (compressed / original)

pub fn savings(&self) -> f64

Get space savings (1.0 - ratio)

pub fn as_compressed(&self) -> &[u8]

Get compressed bytes

pub fn decompress(&mut self) -> Result<&[u8]>

Decompress and get data

First call triggers decompression, subsequent calls use cache.

pub fn decompress_owned(&self) -> Result<Vec<u8>>

Force decompress and return owned data

pub fn is_cached(&self) -> bool

Check if already decompressed (cached)

pub fn clear_cache(&mut self)

Clear the decompression cache

pub fn from_compressed(compressed: Vec<u8>, original_size: u32) -> Self

Create from pre-compressed data

pub fn to_wire(&self) -> Vec<u8>

Serialize to wire format: [compressed_data_with_prepended_size...]

pub fn from_wire(data: &[u8]) -> Result<Self>

Parse from wire format

Trait Implementations

impl Debug for DxCompressed

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

Formats the value using the given formatter.

impl Default for DxCompressed

fn default() -> Self

Returns the “default value” for a type.
