Struct ThemeGeometry 

#[non_exhaustive]
pub struct ThemeGeometry {
    pub radius: Option<f32>,
    pub radius_lg: Option<f32>,
    pub frame_width: Option<f32>,
    pub disabled_opacity: Option<f32>,
    pub border_opacity: Option<f32>,
    pub scroll_width: Option<f32>,
    pub shadow: Option<bool>,
}

Geometric properties for UI elements.

Controls border radius, frame widths, and opacity values that vary across platform themes.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

radius: Option<f32>

Corner radius for rounded elements (in logical pixels).

radius_lg: Option<f32>

Larger corner radius for dialogs, cards, and panels (in logical pixels).

frame_width: Option<f32>

Window/widget frame border width (in logical pixels).

disabled_opacity: Option<f32>

Opacity multiplier for disabled elements (0.0 = invisible, 1.0 = fully opaque).

border_opacity: Option<f32>

Opacity multiplier for borders (0.0 = invisible, 1.0 = fully opaque).

scroll_width: Option<f32>

Scrollbar track width (in logical pixels).

shadow: Option<bool>

Whether the platform uses drop shadows on windows and popups.

Implementations

impl ThemeGeometry

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 ThemeGeometry

fn clone(&self) -> ThemeGeometry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThemeGeometry

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

Formats the value using the given formatter.

impl Default for ThemeGeometry

fn default() -> ThemeGeometry

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ThemeGeometry

where ThemeGeometry: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ThemeGeometry

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
