Struct ChartGpuState 

pub struct ChartGpuState { /* private fields */ }

GPU state for chart rendering.

Manages all GPU resources needed for efficient chart rendering:

• Transform uniform buffer
• Per-series vertex buffers
• Grid line buffers

Implementations

impl ChartGpuState

pub fn update( &mut self, chart: &Chart, bounds: &Rect, viewport_size: Vec2, dirty_flags: ChartDirtyFlags, )

Update GPU state from chart and cache.

pub fn update_from_prepare_result( &mut self, chart: &Chart, bounds: &Rect, viewport_size: Vec2, result: &PrepareResult, )

Update GPU state from streaming chart prepare result.

pub fn transform_bind_group(&self) -> &BindGroup

Get the transform bind group.

pub fn transform_bind_group_layout(&self) -> &BindGroupLayout

Get the transform bind group layout.

pub fn transform(&self) -> &ChartTransform
