Struct DctStreamingDecoder 

pub struct DctStreamingDecoder { /* private fields */ }

Streaming decoder for DCTDecode (JPEG).

Since JPEG requires the full input to decode, this accumulates bytes and performs the actual decode in finish().

Implementations

impl DctStreamingDecoder

pub fn new() -> Self

Create a new streaming DCT decoder.

Trait Implementations

impl Default for DctStreamingDecoder

fn default() -> Self

Returns the “default value” for a type.

impl StreamingDecoder for DctStreamingDecoder

fn feed(&mut self, input: &[u8]) -> Result<(), DecodeError>

Feed a chunk of compressed input data.

fn finish(&mut self) -> Result<(), DecodeError>

Signal that all input has been provided and perform final flush.

fn output_available(&self) -> usize

Returns the number of decompressed bytes available to read.

fn read_output(&mut self, buf: &mut [u8]) -> usize

Read decompressed output into the provided buffer. Returns the number of bytes actually written to buf.
