Struct ImageLoader 

pub struct ImageLoader { /* private fields */ }

Background image loader with request/poll/get API.

• request() — enqueue a fetch (callable from render with &self)
• poll() — drain completed fetches into cache (callable from event loop with &mut self)
• get() — read from cache (callable from render with &self)

Implementations

impl ImageLoader

pub fn new() -> Self

pub fn request(&self, uri: &str, speaker_ip: IpAddr)

Request an image fetch if not already cached or pending.

Callable from render functions with &self. The fetch happens in a background thread; call poll() from the event loop to collect results.

pub fn poll(&mut self) -> bool

Drain completed fetches into the cache. Call from event loop each tick.

Returns true if any new images were loaded (should mark app dirty).

pub fn get(&self, uri: &str) -> Option<&DynamicImage>

Get a cached image by URI.
