Struct ShapeRecorder 

pub struct ShapeRecorder { /* private fields */ }

The POD half of a recording as it is written: the shape records with their brush and stop tables and coalesced segments, and the bounds those records reach. Plain data throughout, so a scene carries one across threads; CommandRecording wraps it with the other lane.

Implementations

impl ShapeRecorder

pub fn tables(&self) -> &RecordTables

The owned shape columns and their brush, stop and segment tables.

pub fn is_empty(&self) -> bool

pub fn all_segments(&self) -> Range<u32>

Every segment, the range a run of the whole recording draws.

pub fn bounds(&self) -> Option<Rect>

The rect every recorded shape’s pixels lie within; None when nothing was recorded.

pub fn fingerprint(&self) -> u64

The tables’ fingerprint; see RecordTables::fingerprint.

pub fn clear(&mut self)

Empties the recorder while retaining its table capacities.

pub fn push_primitive(&mut self, primitive: DrawPrimitive) -> Recorded

Records a rect, rounded rect or arc, blended or not; hands any other primitive back untouched.

pub fn push_shape_primitive( &mut self, primitive: DrawPrimitive, blend_mode: BlendMode, ) -> Recorded

Records a rect, rounded rect or arc with the supplied blend mode. Returns any other primitive untouched, including blend wrappers.

pub fn push_rect( &mut self, rect: Rect, brush: &Brush, stroke: Option<Stroke>, blend: BlendMode, ) -> Rect

pub fn push_round_rect( &mut self, rect: Rect, brush: &Brush, radii: CornerRadii, stroke: Option<Stroke>, blend: BlendMode, ) -> Rect

pub fn push_arc(&mut self, rect: Rect, args: &ArcRecordArgs<'_>) -> Rect

Records an arc band or annular sector with the rect the primitive carries.

pub fn push_scope_arc( &mut self, args: &ArcRecordArgs<'_>, geometry: &ArcGeometry, ) -> Rect

Records an arc the draw scope drew, whose band the scope already normalised: the record keeps the disc around the band as its rect and derives the primitive’s tight bounds only when asked.

Trait Implementations

fn clone(&self) -> ShapeRecorder

impl Default for ShapeRecorder

fn default() -> Self

Returns the “default value” for a type.
