Struct ResidentPage 

pub struct ResidentPage {
    pub key: u64,
    pub extent_px: (u32, u32),
    pub scale: f32,
}

One retained page the renderer holds resident: the key it was recorded under (Command::PushRetained’s key), its rasterized extent in physical pixels and the scale it was rasterized at.

Both are the page as rasterized: the bracket’s rectangle mapped through its transform with the presentation scale applied, so scale is the device scale times the bracket’s own scale (see frust_engine::cache::retained). A page is reusable by a DrawRetained with the same linear transform at any alpha and any translation, and by nothing else.

Fields

key: u64

The raw retained key.

extent_px: (u32, u32)

The page’s extent in physical pixels.

scale: f32

The device scale the page was rasterized at.
