Struct ShapeRenderer 

pub struct ShapeRenderer { /* private fields */ }

Per-frame shape geometry collector.

Implementations

impl ShapeRenderer

pub fn new( gpu: &GpuContext, format: TextureFormat, width: f32, height: f32, sample_count: u32, ) -> Self

Create a new shape renderer with the given GPU context and surface format.

pub fn begin_frame(&mut self)

Clear geometry for a new frame.

pub fn set_viewport(&mut self, width: f32, height: f32)

Update the viewport size.

pub fn fill_rect(&mut self, rect: Rect, color: Color, corner_radius: f32)

Add a filled rectangle.

pub fn stroke_rect( &mut self, rect: Rect, color: Color, width: f32, corner_radius: f32, )

Add a stroked rectangle.

pub fn stroke_rounded_rect( &mut self, rect: Rect, color: Color, width: f32, corner_radius: f32, bg_color: Color, )

Stroke a rounded rectangle with proper inner cutout.

When bg_color is not transparent, the inner region is filled with that color, producing a proper stroked appearance on any background.

pub fn fill_circle(&mut self, center: Position, radius: f32, color: Color)

Add a filled circle.

pub fn stroke_circle( &mut self, center: Position, radius: f32, color: Color, width: f32, )

Add a stroked circle.

pub fn fill_rect_gradient( &mut self, rect: Rect, gradient: &Gradient, corner_radius: f32, )

Fill a rectangle with a gradient (linear or radial).

Gradient colors are interpolated across the rectangle’s vertices.

pub fn shadow_rect(&mut self, rect: Rect, shadow: &Shadow, corner_radius: f32)

Draw a shadow behind a rectangle.

pub fn draw_image(&mut self, _handle: &ImageHandle, _rect: Rect)

Draw an image (placeholder — textures require a separate pipeline).

pub fn line(&mut self, from: Position, to: Position, color: Color, width: f32)

Add a line segment.

pub fn flush(&mut self, gpu: &GpuContext, pass: &mut RenderPass<'_>)

Flush geometry and encode draw commands into the given render pass.

pub fn vertex_count(&self) -> usize

Current vertex count for statistics.

pub fn index_count(&self) -> usize

Current index/triangle count for statistics.

pub fn sample_count(&self) -> u32

MSAA sample count configured for this renderer.
