Implementations

impl ZstdCodec

pub const fn new(compression: CompressionLevel, checksum: bool) -> Self

Create a new Zstd codec.

pub fn new_with_configuration(configuration: &ZstdCodecConfiguration) -> Self

Create a new Zstd codec from configuration.

Trait Implementations

impl BytesToBytesCodecTraits for ZstdCodec

fn recommended_concurrency( &self, _decoded_representation: &BytesRepresentation ) -> Result<RecommendedConcurrency, CodecError>

Return the maximum internal concurrency supported for the requested decoded representation.

fn encode( &self, decoded_value: Vec<u8>, _options: &CodecOptions ) -> Result<Vec<u8>, CodecError>

Encode chunk bytes.

fn decode( &self, encoded_value: Vec<u8>, _decoded_representation: &BytesRepresentation, _options: &CodecOptions ) -> Result<Vec<u8>, CodecError>

Decode chunk bytes.

fn partial_decoder<'a>( &self, r: Box<dyn BytesPartialDecoderTraits + 'a>, _decoded_representation: &BytesRepresentation, _options: &CodecOptions ) -> Result<Box<dyn BytesPartialDecoderTraits + 'a>, CodecError>

Initialises a partial decoder.

fn async_partial_decoder<'a, 'life0, 'life1, 'async_trait>( &'a self, r: Box<dyn AsyncBytesPartialDecoderTraits + 'a>, _decoded_representation: &'life0 BytesRepresentation, _options: &'life1 CodecOptions ) -> Pin<Box<dyn Future<Output = Result<Box<dyn AsyncBytesPartialDecoderTraits + 'a>, CodecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Available on crate feature async only.

Initialises an asynchronous partial decoder.

fn compute_encoded_size( &self, decoded_representation: &BytesRepresentation ) -> BytesRepresentation

Returns the size of the encoded representation given a size of the decoded representation.

impl Clone for ZstdCodec

fn clone(&self) -> ZstdCodec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CodecTraits for ZstdCodec

fn create_metadata_opt( &self, _options: &ArrayMetadataOptions ) -> Option<Metadata>

Create metadata.

fn partial_decoder_should_cache_input(&self) -> bool

Indicates if the input to a codecs partial decoder should be cached for optimal performance. If true, a cache may be inserted before it in a CodecChain partial decoder.

fn partial_decoder_decodes_all(&self) -> bool

Indicates if a partial decoder decodes all bytes from its input handle and its output should be cached for optimal performance. If true, a cache will be inserted at some point after it in a CodecChain partial decoder.

fn create_metadata(&self) -> Option<Metadata>

Create metadata with default options.

impl Debug for ZstdCodec

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

Formats the value using the given formatter.
