Tuple Fields

Implementations

impl Images

pub fn register(&mut self, hash: AssetHash, asset: &Asset)

Hand asset’s bytes to the browser under hash. Idempotent: a hash already held is left as it is, so re-sent bytes cost nothing.

pub fn holds(&self, hash: AssetHash) -> bool

Whether the bytes behind hash have been registered.

pub fn draw( &self, ctx: &CanvasRenderingContext2d, rect: Rect, hash: AssetHash, ) -> Repaint

The artwork registered under hash, filling rect. A mark whose ink is still decoding draws nothing and owes the caller a frame.
