Struct SemanticNode 

pub struct SemanticNode {
    pub id: Id,
    pub role: Role,
    pub label: Option<String>,
    pub rect: Rect,
    pub children: Vec<Id>,
    pub focused: bool,
    pub disabled: bool,
    pub value: Option<f32>,
    pub min_value: Option<f32>,
    pub max_value: Option<f32>,
}

A node in the semantic/accessibility tree. This exists independently of the draw order and describes the “meaning” of the UI.

Fields

id: Id

The unique, persistent ID of the widget.

role: Role

The semantic role of the widget.

label: Option<String>

The human-readable label or description (e.g. Button text).

rect: Rect

The screen-space bounding box.

children: Vec<Id>

The IDs of children nodes in the semantic hierarchy.

focused: bool

Whether this node is currently focused by the keyboard.

disabled: bool

Whether this node is currently disabled (non-interactive).

value: Option<f32>

Current numeric value (for sliders, progress bars, etc).

min_value: Option<f32>

Minimum numeric value.

max_value: Option<f32>

Maximum numeric value.

Implementations

impl SemanticNode

pub fn new(id: Id, role: Role, rect: Rect) -> Self

pub fn with_label(self, label: impl Into<String>) -> Self

pub fn with_focus(self, focused: bool) -> Self

pub fn with_value(self, value: f32) -> Self

pub fn with_min_value(self, min: f32) -> Self

pub fn with_max_value(self, max: f32) -> Self

Trait Implementations

impl Clone for SemanticNode

fn clone(&self) -> SemanticNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticNode

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

Formats the value using the given formatter.

impl PartialEq for SemanticNode

fn eq(&self, other: &SemanticNode) -> 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.
