Struct AsyncImageLoader 

pub struct AsyncImageLoader { /* private fields */ }

A high-level manager that handles loading and caching multiple asynchronous images.

Implementations

impl AsyncImageLoader

pub fn new() -> Self

Creates a new asynchronous image loader.

pub fn load(&mut self, path: impl Into<String>)

Triggers the loading of an image from the specified path, if it is not already loaded or loading.

pub fn progress(&mut self, ctx: &mut Context) -> (usize, usize)

Updates the loading state and returns (loaded_count, total_count).

Both successfully loaded and failed assets count as “done”.

pub fn progress_ratio(&mut self, ctx: &mut Context) -> f32

Returns the loading progress ratio from 0.0 to 1.0.

pub fn is_done(&mut self, ctx: &mut Context) -> bool

Checks if all queued images have finished loading (either successfully or with error).

pub fn is_ready(&mut self, ctx: &mut Context, path: &str) -> bool

Checks if a specific image has finished loading and is ready for rendering.

pub fn get(&mut self, ctx: &mut Context, path: &str) -> Option<Image>

Retrieves the loaded image handle if it is ready, otherwise returns None.

pub fn get_or( &mut self, ctx: &mut Context, path: &str, fallback: Image, ) -> Image

Retrieves the loaded image if ready, otherwise returns the specified fallback image.

pub fn error(&self, path: &str) -> Option<&str>

Checks if loading failed for a specific path, returning the error message if any.

Formats the value using the given formatter.

impl Default for AsyncImageLoader

fn default() -> AsyncImageLoader

Returns the “default value” for a type.
