Struct WasmMediaCache 

Source 
pub struct WasmMediaCache {
    pub document_version: u64,
    pub geometry: Option<MediaGeometry>,
    pub blocks: Vec<(Arc<MediaBlock>, u32, u16)>,
}
Expand description

Per-buffer cache of a media plugin’s blocks, resolved and sized.

Fields§

§document_version: u64

Document version the blocks were produced against — the staleness key.

§geometry: Option<MediaGeometry>

IM.7a: the geometry the blocks were SIZED against, so a window resize re-measures. Without this a block keeps the row count it earned at the old pane width: widen the window and a Contain image is drawn larger inside a box still reserved for the smaller one.

§blocks: Vec<(Arc<MediaBlock>, u32, u16)>

One entry per block: the descriptor plus the rows it reserves.
