Struct WidgetBorderSpec 

pub struct WidgetBorderSpec {
    pub color: Option<Rgba>,
    pub corner_radius: Option<f32>,
    pub line_width: Option<f32>,
    pub shadow_enabled: Option<bool>,
    pub padding_top: Option<f32>,
    pub padding_right: Option<f32>,
    pub padding_bottom: Option<f32>,
    pub padding_left: Option<f32>,
}

Widget-level border specification: color, geometry, and padding.

Used on per-widget structs for border properties specific to individual widgets. Unlike DefaultsBorderSpec, includes the four padding sides (widget-level layout) but omits corner_radius_lg and opacity (defaults-only geometry).

Padding fields are widget-only because different widgets need different internal padding even when sharing the same border geometry from defaults.

Padding is per side. A platform states padding side by side, and some sides differ (Windows’ input is 10 left / 6 right, docs/platform-facts.md §2.4), so the model stores the four sides and nothing else. None means the platform states no value for that side; Some(0.0) means it states zero.

TOML. The sides are padding_top_px, padding_right_px, padding_bottom_px and padding_left_px. padding_horizontal_px and padding_vertical_px are parse-time shorthand that set both sides of their axis. A table that states an axis key together with one of that axis’s sides is a parse error naming both keys. Serialisation writes sides only.

All fields are optional to support partial overlays, and they merge per field, the overlay winning, so a reader’s left side over a preset’s shorthand replaces the left side alone.

Fields

color: Option<Rgba>

Border color.

corner_radius: Option<f32>

Corner radius in logical pixels.

line_width: Option<f32>

Border stroke width in logical pixels.

shadow_enabled: Option<bool>

Whether the bordered element has a drop shadow.

padding_top: Option<f32>

Padding inside the border above the content, in logical pixels.

padding_right: Option<f32>

Padding inside the border right of the content, in logical pixels.

padding_bottom: Option<f32>

Padding inside the border below the content, in logical pixels.

padding_left: Option<f32>

Padding inside the border left of the content, in logical pixels.

Implementations

impl WidgetBorderSpec

pub fn merge(&mut self, overlay: &Self)

Merge an overlay into this value. Some fields in the overlay replace the corresponding fields in self; None fields are left unchanged. Nested structs are merged recursively.

pub fn is_empty(&self) -> bool

Returns true if all fields are at their default (None/empty) state.

Trait Implementations

impl Clone for WidgetBorderSpec

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WidgetBorderSpec

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

Formats the value using the given formatter.

impl Default for WidgetBorderSpec

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WidgetBorderSpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WidgetBorderSpec

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for WidgetBorderSpec

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

where __S: Serializer,
