Implementations

impl StreamingDecoder

pub fn new() -> StreamingDecoder

Creates a new StreamingDecoder

Allocates the internal buffers.

pub fn reset(&mut self)

Resets the StreamingDecoder

pub fn update( &mut self, buf: &[u8], image_data: &mut Vec<u8>, ) -> Result<(usize, Decoded), DecodingError>

Low level StreamingDecoder interface.

Allows to stream partial data to the encoder. Returns a tuple containing the bytes that have been consumed from the input buffer and the current decoding result. If the decoded chunk was an image data chunk, it also appends the read data to image_data.
