Struct Theme 

pub struct Theme { /* private fields */ }

A fully resolved theme, ready to style widgets.

Implementations

impl Theme

pub fn id(&self) -> &str

The theme id, which is its file stem.

pub fn name(&self) -> &str

The display name from [meta] name.

pub fn color(&self, token: &str) -> Option<Rgb>

A colour token such as "accent".

pub fn solid(&self, expression: &str) -> Result<Rgb, String>

Resolves a colour written the way theme files write it ("$danger", "#38BDF8", "mix($accent, $danger, 50%)") against this theme’s tokens.

Errors

A message explaining why expression is not a single colour: it does not parse, names an unknown token, or uses pulse(), which breathes and so has no single colour.

pub fn series_color(&self, index: usize) -> Rgb

The tone of the index-th series of a chart, counted from zero.

A theme carries SERIES_COLORS series tones, so the tones wrap around: series five takes the tone of series zero. Wrapping is why a chart must name its series with a Legend instead of leaving the meaning in the colour, and why a chart that needs more than five kinds is better off grouping the small ones together.

pub fn colors(&self) -> impl Iterator<Item = (&str, Rgb)>

Every colour token, sorted by name.

pub fn motion(&self) -> Motion

Motion timing.

pub fn typography(&self, role: &str) -> Option<&StyleProps>

A typography role such as "title".

pub fn icon_set(&self) -> &str

The icon set this theme uses.

pub fn icon_overrides(&self) -> &BTreeMap<String, IconGlyphs>

Icons this theme overrides on top of its icon set.

pub fn animation_overrides(&self) -> &BTreeMap<String, Arc<CellAnimation>>

Animations this theme defines or replaces on top of its icon set’s.

pub fn style( &self, widget: &str, variant: Option<&str>, states: &[State], ) -> StyleProps

The style of widget drawn with variant in states: every matching rule layered from least to most specific.

The result is remembered for the lifetime of the theme, so asking again (as widgets do every frame) is a lookup, and the returned properties share their storage.
