Enum SemanticsRole 

pub enum SemanticsRole {
    Layout,
    Subcompose,
    Text {
        value: String,
    },
    Spacer,
    Button,
    Unknown,
}

Semantic role describing how a node should participate in accessibility and hit testing. Roles are now derived from SemanticsConfiguration rather than widget types.

Variants

Layout

Generic container or layout node

Subcompose

Subcomposition boundary

Text

Text content (derived from TextNode for backward compatibility)

Fields

value: String

Spacer

Spacer (non-interactive)

Button

Button (derived from is_button semantics flag)

Unknown

Unknown or unspecified role

Trait Implementations

impl Clone for SemanticsRole

fn clone(&self) -> SemanticsRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticsRole

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

Formats the value using the given formatter.

impl PartialEq for SemanticsRole

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