Implementations

impl StreamingDecoder[src]

pub fn new() -> StreamingDecoder[src]

Creates a new streaming decoder

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

Updates the internal state of the decoder.

Returns the number of bytes consumed from the input buffer and the last decoding result.

pub fn last_ext(&self) -> (u8, &[u8], bool)[src]

Returns the data of the last extension that has been decoded.

pub fn current_frame_mut<'a>(&'a mut self) -> &'a mut Frame<'static>[src]

Current frame info as a mutable ref.

pub fn current_frame<'a>(&'a self) -> &'a Frame<'static>[src]

Current frame info as a ref.

pub fn width(&self) -> u16[src]

Width of the image

pub fn height(&self) -> u16[src]
