Struct WidgetMetrics 

#[non_exhaustive]
pub struct WidgetMetrics {
    pub button: ButtonMetrics,
    pub checkbox: CheckboxMetrics,
    pub input: InputMetrics,
    pub scrollbar: ScrollbarMetrics,
    pub slider: SliderMetrics,
    pub progress_bar: ProgressBarMetrics,

    pub menu_item: MenuItemMetrics,
    pub tooltip: TooltipMetrics,
    pub list_item: ListItemMetrics,
    pub toolbar: ToolbarMetrics,
    pub splitter: SplitterMetrics,
}

Per-widget sizing and spacing metrics.

Contains sub-structs for each widget type with platform-specific dimensions. All sub-structs are nested (not Option) because they default to empty (all fields None). Empty sub-structs are omitted from serialized output.

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.

button: ButtonMetrics

Button sizing and spacing.

checkbox: CheckboxMetrics

Checkbox and radio button sizing.

input: InputMetrics

Text input field sizing.

scrollbar: ScrollbarMetrics

Scrollbar sizing.

slider: SliderMetrics

Slider/range control sizing.

progress_bar: ProgressBarMetrics

Progress bar sizing.

tab: TabMetrics

Tab bar sizing.

menu_item: MenuItemMetrics

Menu item sizing.

tooltip: TooltipMetrics

Tooltip sizing.

list_item: ListItemMetrics

List item / row sizing.

toolbar: ToolbarMetrics

Toolbar sizing.

splitter: SplitterMetrics

Splitter/divider sizing.

Implementations

impl WidgetMetrics

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 WidgetMetrics

fn clone(&self) -> WidgetMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WidgetMetrics

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

Formats the value using the given formatter.

impl Default for WidgetMetrics

fn default() -> WidgetMetrics

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WidgetMetrics

where WidgetMetrics: 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 WidgetMetrics

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
