Struct DrawList 

pub struct DrawList { /* private fields */ }

An ordered buffer of DrawCommands, with integrated clip-stack and bounds tracking.

Build a list with the typed push_* helpers (or the low-level push) then pass it to a RenderBackend::execute call.

Implementations

impl DrawList

pub fn new() -> Self

Construct an empty DrawList.

pub fn push(&mut self, cmd: DrawCommand)

Append an arbitrary DrawCommand, automatically updating clip depth and accumulated bounds.

pub fn len(&self) -> usize

Return the number of commands in the list.

pub fn is_empty(&self) -> bool

Return true if the list contains no commands.

pub fn iter(&self) -> Iter<'_, DrawCommand>

Iterate over all commands in submission order.

pub fn clear(&mut self)

Remove all commands and reset clip depth and bounds.

pub fn bounds(&self) -> Option<Rect>

Return the accumulated axis-aligned bounding box of all non-clip draw commands, or None if no draw commands have been pushed.

pub fn clip_depth(&self) -> usize

Return the current clip-stack depth. Zero means balanced.

pub fn is_clip_balanced(&self) -> bool

Return true if the clip stack is balanced (depth == 0).

pub fn push_rect(&mut self, rect: Rect, color: Color)

Push a solid-filled rectangle.

pub fn push_stroke_rect(&mut self, rect: Rect, thickness: f32, color: Color)

Push a stroked rectangle outline.

pub fn push_rounded_rect(&mut self, rect: Rect, radius: f32, color: Color)

Push a filled rectangle with uniform corner radius.

pub fn push_rounded_rect_per_corner( &mut self, rect: Rect, radii: [f32; 4], color: Color, )

Push a filled rectangle with per-corner radii [tl, tr, br, bl].

pub fn push_circle(&mut self, center: Point, radius: f32, color: Color)

Push a filled circle.

pub fn push_ellipse(&mut self, center: Point, rx: f32, ry: f32, color: Color)

Push a filled ellipse.

pub fn push_line(&mut self, from: Point, to: Point, color: Color)

Push a 1-pixel aliased line segment.

pub fn push_line_aa(&mut self, from: Point, to: Point, color: Color)

Push a 1-pixel anti-aliased line segment.

pub fn push_line_thick( &mut self, from: Point, to: Point, width: f32, color: Color, )

Push a thick, filled line segment.

pub fn push_line_dashed( &mut self, from: Point, to: Point, dash_len: f32, gap_len: f32, color: Color, )

Push a dashed line segment.

pub fn push_clip(&mut self, rect: Rect)

Push a clip rectangle onto the clip stack.

pub fn pop_clip(&mut self)

Pop the top clip rectangle from the clip stack.

pub fn push_path(&mut self, path: PathData, color: Color)

Push a solid-filled path.

pub fn push_stroke_path( &mut self, path: PathData, style: StrokeStyle, color: Color, )

Push a stroked path.

pub fn push_gradient_linear( &mut self, rect: Rect, start: Point, end: Point, stops: Vec<GradientStop>, )

Push a linear gradient fill over rect.

pub fn push_gradient_radial( &mut self, rect: Rect, center: Point, radius: f32, stops: Vec<GradientStop>, )

Push a radial gradient fill over rect.

pub fn push_image(&mut self, image: ImageData, dest: Rect, filter: ImageFilter)

Push a scaled image blit.

pub fn push_nine_slice( &mut self, image: ImageData, dest: Rect, insets: [u32; 4], )

Push a 9-slice scaled image.

pub fn push_shadow( &mut self, rect: Rect, offset: Point, blur_radius: f32, color: Color, )

Push a box shadow.

pub fn push_text( &mut self, rect: Rect, text: impl Into<String>, font: FontSpec, color: Color, )

Push a text draw command.

pub fn push_blend_mode(&mut self, mode: BlendMode)

Set the blend mode for all subsequent draw commands.

The mode remains active until the next push_blend_mode call. The initial mode at the start of every frame is BlendMode::Normal.

pub fn push_backdrop_blur(&mut self, rect: Rect, blur_radius: f32)

Apply a backdrop blur (frosted-glass effect) to the region rect.

Blurs the previously-rendered content behind rect by blur_radius pixels. Subsequent commands draw on top of the blurred result.
