Struct gift::Decoder

pub struct Decoder<R: Read> { /* fields omitted */ }

A builder which can be turned into either a BlockDecoder or a FrameDecoder.

Example

let mut frame_dec = gift::Decoder::new(gif).into_frame_decoder();
let preamble = frame_dec.preamble()?;
println!("preamble: {:?}", preamble);
for frame in frame_dec {
    println!("frame: {:?}", frame?);
}

Methods

impl<R: Read> Decoder<R>

pub fn new(r: R) -> Self

Create a new Decoder

pub fn max_image_sz(self, max_image_sz: Option<usize>) -> Self

Set the maximum image size (in bytes) to allow for decoding.

Important traits for FrameDecoder<R>

impl<R: Read> Iterator for FrameDecoder<R> type Item = Result<Frame, DecodeError>;

pub fn into_frame_decoder(self) -> FrameDecoder<R>

Convert the decoder into a frame decoder.

Trait Implementations

impl<R: Read> IntoIterator for Decoder<R>

type Item = Result<Block, DecodeError>

The type of the elements being iterated over.

type IntoIter = BlockDecoder<R>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Convert the decoder into a block decoder
