}

A paint operation that draws something on screen.

Paint nodes do not participate in layout sizing – their visual output is painted into the bounding box determined by their parent layout node. The renderer walks paint ops to build the final DisplayList.

Variants

DrawRect

Draws a filled and/or stroked rectangle with optional rounded corners and shadow.

This is the workhorse of the paint pipeline – backgrounds, borders, cards, buttons, and dividers all compile down to DrawRect.

Fields

fill: Option<Fill>

The interior fill color. None means the rectangle has no fill (transparent).

stroke: Option<Stroke>

The border stroke. None means no border.

corner_radius: f32

Corner radius in logical pixels. 0.0 means sharp corners.

shadow: Option<BoxShadow>

An optional drop shadow behind the rectangle.

DrawText

Draws a single-style text string.

Use this for simple labels where the entire string shares one style. For mixed-style text (e.g., syntax highlighting), use DrawRichText.

Fields

text: String

The text content to render.

size: f32

Font size in logical pixels.

color: Color

Text foreground color.

underline: bool

Whether to underline the text.

caret_index: Option<usize>

If set, the renderer draws a text cursor at this byte index.

DrawRichText

Draws multi-style (rich) text composed of TextRuns.

Each run can have a different font size, color, underline, and background highlight. Used for code editors, formatted messages, and any text where inline styling varies.

Fields

runs: Vec<TextRun>

The styled text runs, in order.

caret_index: Option<usize>

If set, the renderer draws a text cursor at this byte index (relative to the concatenated run text).

DrawImage

Draws a raster image from a URI or asset path.

Fields

source: String

The image source: a file path, HTTP URL, or asset identifier.

fit: ImageFit

How the image scales to fit its layout box.

DrawPath

Draws an SVG-style path string, optionally filled and/or stroked.

The path uses SVG path data syntax (e.g., "M 0 0 L 10 10 Z").

Fields

path: String

SVG path data string.

fill: Option<Fill>

Optional fill color for the path interior.

stroke: Option<Stroke>

Optional stroke for the path outline.

DrawSvg

Draws inline SVG content, optionally overriding fill and stroke colors.

Fields

content: String

The raw SVG markup as a string.

fill: Option<Fill>

Optional fill color override applied to the SVG elements.

stroke: Option<Stroke>

Optional stroke color override applied to the SVG elements.

Trait Implementations

impl Clone for PaintOp

fn clone(&self) -> PaintOp

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PaintOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PaintOp

fn deserialize<__D>( __deserializer: __D, ) -> Result<PaintOp, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PaintOp

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PaintOp

fn eq(&self, other: &PaintOp) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PaintOp

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
