Struct zstd::stream::raw::Decoder

pub struct Decoder<'a> { /* private fields */ }

An in-memory decoder for streams of data.

Implementations

impl Decoder<'static>

pub fn new() -> Result<Self>

Creates a new decoder.

pub fn with_dictionary(dictionary: &[u8]) -> Result<Self>

Creates a new decoder initialized with the given dictionary.

impl<'a> Decoder<'a>

pub fn with_context(context: &'a mut DCtx<'static>) -> Self

Creates a new decoder which employs the provided context for deserialization.

pub fn with_prepared_dictionary<'b>( dictionary: &DecoderDictionary<'b>, ) -> Result<Self>

where 'b: 'a,

Creates a new decoder, using an existing DecoderDictionary.

pub fn with_ref_prefix<'b>(ref_prefix: &'b [u8]) -> Result<Self>

where 'b: 'a,

Creates a new decoder, using a ref prefix

pub fn set_parameter(&mut self, parameter: DParameter) -> Result<()>

Sets a decompression parameter for this decoder.

Trait Implementations

impl Operation for Decoder<'_>

fn run<C: WriteBuf + ?Sized>( &mut self, input: &mut InBuffer<'_>, output: &mut OutBuffer<'_, C>, ) -> Result<usize>

Performs a single step of this operation.

fn flush<C: WriteBuf + ?Sized>( &mut self, output: &mut OutBuffer<'_, C>, ) -> Result<usize>

Flushes any internal buffer, if any.

fn reinit(&mut self) -> Result<()>

Prepares the operation for a new frame.

fn finish<C: WriteBuf + ?Sized>( &mut self, _output: &mut OutBuffer<'_, C>, finished_frame: bool, ) -> Result<usize>

Finishes the operation, writing any footer if necessary.

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

Performs a single step of this operation.
