Struct Countdown

    pub show_hours: bool,

    pub show_seconds: bool,

#[serde(from = "CountdownRaw")]: box_builder.rs’s width formula for this component (visible * 2*box_w + (visible-1)*gap) doesn’t include the small inner gap (gap*0.3) paint() actually inserts within each digit pair — only the gap between pairs (the separator). That mismatch compounds with every extra group and is exactly what #127 measured (153×67 assigned vs. 187×68 painted). Since paint() draws from self.digit_size/self.gap, not layout.width (same pattern as switch/slider), the fix is to fold the exact formula paint() uses into style.width here, so box_builder.rs’s if css.width.is_none() never gets a chance to apply its slightly-off one.

Trait Implementations

impl Animatable for Countdown

fn animation_effects(&self) -> &[AnimationEffect]

fn timeline_steps(&self) -> &[TimelineStep]

Timed animation steps (timeline field): each step’s animations are resolved with delay += step.at. Empty by default.

impl Debug for Countdown

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Countdown

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Countdown

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Painter for Countdown

fn paint_content( &self, canvas: &Canvas, layout: &BoxLayout, _props: &AnimatedProperties, ctx: &PaintCtx, )

Paint the component’s content into the canvas. The canvas is already translated to the content-box origin and clipped if overflow: hidden was set. Generic decorations (bg, border, shadow) are already painted by the engine.

fn intrinsic_size( &self, _available: AvailableSize, _ctx: &MeasureCtx, ) -> Option<(f32, f32)>

Optional intrinsic measurement for leaves like text, image, codeblock. Return None to let taffy compute the size from the CSS style alone. available mirrors taffy’s AvailableSpace.

impl Serialize for Countdown

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Styled for Countdown

fn style_config(&self) -> &CssStyle

impl StyledMut for Countdown

fn style_config_mut(&mut self) -> &mut CssStyle

impl Timed for Countdown

fn timing(&self) -> (Option<f64>, Option<f64>)
