Struct RecordSegment 

pub struct RecordSegment {
    pub lane: RecordLane,
    pub start: u32,
    pub count: u32,
    pub blend: BlendMode,
    pub gradient: bool,
    pub vertex_gradient: bool,
    pub brushes: u8,
    pub kinds: u8,
    pub band_class: u8,
    pub interiors: bool,
    pub occluders: bool,
    pub bare_interiors: bool,
}

A run of consecutive entries of one lane that a single draw can take: shapes sharing a blend mode and a brush class, or a run of other primitives.

Fields

lane: RecordLane

start: u32

count: u32

blend: BlendMode

gradient: bool

vertex_gradient: bool

Whether the segment’s records are gradients their vertices shade (see ShapeRecord::is_vertex_gradient), which are not gradient: the draw that takes them dithers their fragments.

brushes: u8

One bit per BRUSH_KIND_* present in the segment; bit 0 stands for the records drawn without a brush.

kinds: u8

One bit per FRAGMENT_KIND_* present in the segment.

band_class: u8

The band class every record of the segment is drawn at: the index into ARC_BUCKET_SEGMENTS of the strip each record is instanced over, so one draw covers the segment in record order.

interiors: bool

Whether a rounded fill in the segment has an interior, where coverage is 1 without its distance field, covering at least half of its rect: the only records that repay shading their interior apart.

occluders: bool

Whether a solid fill in the segment has an interior of at least OCCLUDER_MIN_AREA: one a pass lays down ahead of its paint, so what it hides is never shaded.

bare_interiors: bool

Whether a fill in the segment has an interior that repays shading apart (see interiors) that no pass lays down ahead of its paint: a gradient’s or a translucent colour’s.

Implementations

impl RecordSegment

pub fn range(&self) -> Range<usize>

pub fn uniform_kind(&self) -> Option<u32>

The one kind every record of the segment has, if they agree.

pub fn uniform_brush(&self) -> Option<u32>

The one brush kind every record of the segment paints with, if they agree; zero when none of them has a brush.
