pub struct LayerRasterCacheKey { /* private fields */ }

Implementations

impl LayerRasterCacheKey

pub fn source_content( stable_id: Option<NodeId>, content_hash: u64, local_bounds: Rect, pixel_size: (u32, u32), raster_scale: RasterScale, device_phase: Point, ) -> Self

pub fn backdrop_effect( stable_id: Option<NodeId>, input_hash: u64, effect_hash: u64, local_bounds: Rect, pixel_size: (u32, u32), raster_scale: RasterScale, ) -> Self

pub fn layer_effect( stable_id: Option<NodeId>, input_hash: u64, effect_hash: u64, local_bounds: Rect, pixel_size: (u32, u32), raster_scale: RasterScale, ) -> Self

A layer’s render effect applied over its retained surface: the output is a pure function of the surface’s content, the effect and the layer’s pixel rect within the surface.

pub fn scene_range( content_hash: u64, local_bounds: Rect, pixel_size: (u32, u32), raster_scale: RasterScale, ) -> Self

pub fn prefix_snapshot( content_hash: u64, prefix_len: u64, local_bounds: Rect, pixel_size: (u32, u32), raster_scale: RasterScale, ) -> Self

A snapshot of the scene’s rendered prefix: the bytes the target held after drawing ops [0, prefix_len) over the pass’s clear color. A replay of captured bytes is identical to direct rendering by construction — no flattening, so none of the chained-rounding divergence flatten entries carry.

pub fn kind_slot(self) -> usize

Index of this key’s kind in 0..LAYER_RASTER_CACHE_KIND_COUNT, for per-kind accounting.

pub fn stable_id(self) -> Option<NodeId>

pub fn is_scene_range(self) -> bool

pub fn is_source_content(self) -> bool

pub fn identity(self) -> Option<LayerRasterCacheIdentity>

pub fn pixel_size(self) -> (u32, u32)

pub fn local_bounds_bits(self) -> [u32; 4]

The bit pattern of the entry’s local bounds: the place a keyless entry occupies, stable while its content changes.

pub fn raster_scale(self) -> RasterScale

pub fn draws_other_content(self, other: Self) -> bool

Whether other rasterizes other content than this key: another kind, node, content, effect or bounds. Keys that differ only in the scale or the sub-pixel phase they are drawn at hold the same content.
