Struct CommandRecorder 

pub struct CommandRecorder { /* private fields */ }

Mutable command data owned exclusively while a draw scope records it. Publishing with Self::finish shares the completed shape data without copying it.

Implementations

impl CommandRecorder

pub fn from_primitives( primitives: impl IntoIterator<Item = DrawPrimitive>, ) -> Self

Records primitives in order into owned command data.

pub fn reusing(recording: CommandRecording) -> Self

Reuses a completed command’s buffer capacities for an empty recording. Retained readers keep their original shape data.

pub fn finish(self) -> CommandRecording

Publishes completed command data without copying its shape columns.

pub fn len(&self) -> usize

Every recorded entry, including content markers.

pub fn is_empty(&self) -> bool

Whether this recorder contains no entries.

pub fn content_markers(&self) -> u32

The number of recorded content markers.

pub fn clear(&mut self)

Empties the recording, keeping every buffer’s capacity for the next recording into it.

pub fn reserve_shapes(&mut self, additional: usize)

Reserves capacity for additional shape records.

pub fn push_content(&mut self)

Records a content marker at the current command position.

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

Records a primitive the way the draw scope would have: shapes and blended shapes become records, everything else joins the others lane.

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

Records a rectangle with its brush, optional stroke and blend mode.

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

Records a rounded rectangle with its corner radii and paint.

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

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

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

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.

pub fn push_other(&mut self, primitive: DrawPrimitive)

Records a primitive in the non-shape lane and updates its metadata.

pub fn merge_summary(&mut self, other: RecordingSummary)

Folds other’s summary into this recording’s, for callers that combine recordings.

Trait Implementations
