Implementations

impl WidgetInfo

pub fn new(typ: WidgetType) -> Self

pub fn labeled(typ: WidgetType, label: impl ToString) -> Self

pub fn selected(typ: WidgetType, selected: bool, label: impl ToString) -> Self

checkboxes, radio-buttons etc

pub fn drag_value(value: f64) -> Self

pub fn slider(value: f64, label: impl ToString) -> Self

pub fn text_edit(
prev_text_value: impl ToString,
text_value: impl ToString
) -> Self

pub fn text_selection_changed(
text_selection: RangeInclusive<usize>,
current_text_value: impl ToString
) -> Self

pub fn description(&self) -> String

This can be used by a text-to-speech system to describe the widget.

Trait Implementations

impl Clone for WidgetInfo

fn clone(&self) -> WidgetInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WidgetInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WidgetInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
__D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<WidgetInfo> for WidgetInfo

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for WidgetInfo

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

Serialize this value into the given Serde serializer.
