Struct ZstdCodec 

pub struct ZstdCodec { /* private fields */ }

Zstandard codec combining compression and decompression.

Implementations

impl ZstdCodec

pub fn new() -> Self

Create a new Zstd codec with default settings.

pub fn with_level(level: CompressionLevel) -> Self

Create with compression level.

Trait Implementations

impl Clone for ZstdCodec

fn clone(&self) -> ZstdCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Codec for ZstdCodec

fn new() -> Self

Create a new codec with default settings.

fn with_level(level: CompressionLevel) -> Self

Create a new codec with specified level.

fn verify_roundtrip(&self, data: &[u8]) -> Result<bool, Error>

Round-trip test: compress then decompress. Returns true if data matches.

fn measure_ratio(&self, data: &[u8]) -> Result<CompressionRatio, Error>

Get compression ratio for given data.

impl Compressor for ZstdCodec

fn algorithm(&self) -> Algorithm

Get the compression algorithm.

fn level(&self) -> CompressionLevel

Get the configured compression level.

fn compress(&self, input: &[u8]) -> Result<Vec<u8>>

Compress data in one shot.

fn compress_to(&self, input: &[u8], output: &mut [u8]) -> Result<usize>

Compress data into existing buffer.

fn max_compressed_size(&self, input_len: usize) -> usize

Calculate maximum compressed size for input length. Useful for pre-allocating output buffers.

fn stats(&self) -> Option<CompressionStats>

Get compression statistics after operation.

impl Debug for ZstdCodec

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

Formats the value using the given formatter.

impl Decompressor for ZstdCodec

fn algorithm(&self) -> Algorithm

Get the decompression algorithm.

fn decompress(&self, input: &[u8]) -> Result<Vec<u8>>

Decompress data in one shot.

fn decompress_to(&self, input: &[u8], output: &mut [u8]) -> Result<usize>

Decompress data into existing buffer.

fn stats(&self) -> Option<CompressionStats>

Get decompression statistics after operation.

fn decompress_with_size( &self, input: &[u8], output_size: usize, ) -> Result<Vec<u8>, Error>

Decompress with known output size (more efficient).

impl Default for ZstdCodec

fn default() -> Self

Returns the “default value” for a type.
