Struct ShapeRecords 

pub struct ShapeRecords { /* private fields */ }

Recorded shapes stored in parallel columns, ready for GPU upload.

Angle changes leave the body column intact. Original line and arc arguments remain on the CPU so materialisation preserves exactly what the caller supplied; the rects, round rects and path slices that make up most recordings have none, and keep no column for them.

Implementations

impl ShapeRecords

pub fn len(&self) -> usize

The number of recorded shapes.

pub fn is_empty(&self) -> bool

Whether the recording has no shapes.

pub fn bodies(&self) -> &[ShapeRecordBody]

The angle-independent column, directly usable as GPU instance data.

pub fn curves(&self) -> &[ShapeRecordCurve]

The radius and angle column, directly usable as GPU instance data.

pub fn occludes(&self, index: usize) -> bool

Whether the record at index is an opaque fill whose interior is worth laying down ahead of later paint: the test that marks a segment’s occluders. false past the end.

pub fn get(&self, index: usize) -> Option<ShapeRecord>

Reconstructs one complete record, including the original arc arguments.

pub fn iter( &self, ) -> impl ExactSizeIterator<Item = ShapeRecord> + DoubleEndedIterator + '_

Iterates over complete records in draw order without allocating.
