}

A contiguous run of one primitive type that the renderer draws in one call.

The ranges index the matching vector in Scene. A batch never mixes primitive types.

Variants

Shadows

Shadows, drawn with or without corner smoothing as a unit.

Fields

range: Range<usize>

The indices into Scene::shadows.

smoothed: bool

Whether the shadows use corner smoothing.

Quads

Quads, drawn with or without corner smoothing as a unit.

Fields

range: Range<usize>

The indices into Scene::quads.

smoothed: bool

Whether the quads use corner smoothing.

Paths

Paths. The renderer rasterizes their vertices, then composites the results as sprites.

Fields

range: Range<usize>

The indices into Scene::paths.

rasterization_vertex_count: usize

The number of path vertices to rasterize in this batch.

sprite_count: usize

The number of sprites that composite the rasterized paths.

Underlines(Range<usize>)

Underlines, as indices into Scene::underlines.

MonochromeSprites

Single-color sprites that all read from one atlas texture.

Fields

texture_id: AtlasTextureId

The atlas texture that the sprites read from.

range: Range<usize>

The indices into Scene::monochrome_sprites.

SubpixelSprites

Subpixel-antialiased sprites that all read from one atlas texture.

Fields

texture_id: AtlasTextureId

The atlas texture that the sprites read from.

range: Range<usize>

The indices into Scene::subpixel_sprites.

PolychromeSprites

Full-color sprites that all read from one atlas texture.

Fields

texture_id: AtlasTextureId

The atlas texture that the sprites read from.

range: Range<usize>

The indices into Scene::polychrome_sprites.

smoothed: bool

Whether the sprites use corner smoothing.

Surfaces(Range<usize>)

Surfaces, as indices into Scene::surfaces.

BackdropFilters(Range<usize>)

Backdrop filters, as indices into Scene::backdrop_filters.

FilterBoundary(usize)

A filter or grouped-opacity boundary, as an index into Scene::filter_boundaries.
