}

Platform-agnostic theme contract.

Defines all visual constants that must be consistent across platforms. The Rust renderer (render2d.rs) derives CanvasTheme from this. JavaScript hosts consume it via get_theme_json() WASM API.

Fields

canvas_bg: String

Canvas background color (the drawing surface)

grid_color: String

Grid overlay color (dots/lines)

selection_accent: String

Selection highlight accent (handle dots, selection box)

smart_guide_color: String

Smart guide line color

panel_bg: String

Panel background (layers, properties, toolbar)

panel_border: String

Panel border / separator color

text_primary: String

Primary text color (labels, headings)

text_secondary: String

Secondary text color (captions, hints)

accent: String

Primary accent color (buttons, links, active states)

placeholder_border: String

Generic node placeholder border

placeholder_bg: String

Generic node placeholder background

placeholder_text: String

Generic node placeholder text

font_family: String

Default font family stack

font_size_base: f32

Base font size in px

border_radius: f32

Default border radius in px

Implementations

impl ThemeContract

pub fn light() -> Self

Light theme — Apple HIG-inspired warm white.

pub fn dark() -> Self

Dark theme — macOS Catppuccin Mocha-inspired.

pub fn to_json(&self) -> String

Serialize to JSON for JavaScript consumption.

Trait Implementations

impl Clone for ThemeContract

fn clone(&self) -> ThemeContract

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThemeContract

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ThemeContract

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ThemeContract

fn eq(&self, other: &ThemeContract) -> 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 ThemeContract

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
