impl StreamingDecoder
sourcepub fn new() -> StreamingDecoder
pub fn new() -> StreamingDecoder
Creates a new StreamingDecoder
Allocates the internal buffers.

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