ShapeRecords

Struct ShapeRecords 

Source
pub struct ShapeRecords { /* private fields */ }
Expand description

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

Angle changes leave the body column intact. Original arc arguments remain on the CPU so materialisation preserves exactly what the caller supplied.

Implementations§

Source§

impl ShapeRecords

Source

pub fn len(&self) -> usize

The number of recorded shapes.

Source

pub fn is_empty(&self) -> bool

Whether the recording has no shapes.

Source

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

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

Source

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

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

Source

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

Reconstructs one complete record, including the original arc arguments.

Source

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

Iterates over complete records in draw order without allocating.
