Struct ImageLoader 

pub struct ImageLoader { /* private fields */ }

ImageLoader decodes encoded images into drawable Images with registered decoders.

Decoders are tried in the order given; put the platform’s native decoder first and a software one after it. The loader is cheap to clone and every clone shares the same decoders and, with with_worker (the worker feature), the same worker thread.

Implementations

impl ImageLoader

pub fn new(images: ImageContext, decoders: Vec<Box<dyn Decoder>>) -> Self

new decodes on the polling thread: each Pending does its work inside its first poll.

This is the shape for hosts without threads, such as the web, and for hosts whose executor already runs on a background thread. Nothing is spawned.

pub fn decode( &self, encoded: Arc<[u8]>, options: DecodeOptions, ) -> Pending<'static, Image>

decode produces the first frame of encoded as an image: the still-image path.

pub fn open( &self, encoded: Arc<[u8]>, options: DecodeOptions, ) -> Pending<'static, Codec>

open reads the image’s header and returns a Codec that decodes frames on demand.

Use it when frame count or repetition matter — animations — or to defer the first decode.

Trait Implementations

impl Clone for ImageLoader

fn clone(&self) -> ImageLoader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
