pub unsafe fn init_from_table(table: Table<'a>) -> Self

pub fn create<'bldr: 'args, 'args: 'mut_bldr, 'mut_bldr, A: Allocator + 'bldr>( _fbb: &'mut_bldr mut FlatBufferBuilder<'bldr, A>, args: &'args SemanticNodeArgs<'args>, ) -> WIPOffset<SemanticNode<'bldr>>

pub fn node_id(&self) -> &'a str

pub fn role(&self) -> &'a str

ARIA role (e.g., “button”, “heading”, “navigation”, “main”). Validated against WAI-ARIA 1.2 role list by the validator.

pub fn label(&self) -> Option<&'a str>

Human-readable accessible label. For buttons/links: the text announced by screen readers. For images: the alt text equivalent. For headings: usually matches the visible text.

pub fn labelled_by(&self) -> Option<&'a str>

Reference to another node whose content labels this node (aria-labelledby).

pub fn described_by(&self) -> Option<&'a str>

Reference to a node providing extended description (aria-describedby).

pub fn controls(&self) -> Option<&'a str>

Reference to a node this element controls (aria-controls).

pub fn owned_by(&self) -> Option<&'a str>

Reference to a node that owns this element (aria-owns).

pub fn heading_level(&self) -> i8

Heading level (1-6). Only valid when role = “heading”.

pub fn tab_index(&self) -> i32

Tab index for keyboard focus order. -1 = focusable but not in tab order (programmatic focus only). 0 = focusable in natural tab order.

0 = explicit order (discouraged but supported).

pub fn hidden(&self) -> bool

Whether this element is currently hidden from the a11y tree.

pub fn aria_expanded(&self) -> i8

ARIA states (set dynamically by state machines).

pub fn aria_selected(&self) -> i8

pub fn aria_checked(&self) -> i8

pub fn aria_disabled(&self) -> bool

pub fn aria_required(&self) -> bool

pub fn aria_invalid(&self) -> bool

pub fn aria_value_min(&self) -> f32

For range widgets (slider, progressbar, spinbutton).

pub fn aria_value_max(&self) -> f32

pub fn aria_value_now(&self) -> f32

pub fn aria_value_text(&self) -> Option<&'a str>

pub fn custom_aria(&self) -> Option<Vector<'a, ForwardsUOffset<KeyValue<'a>>>>

Custom ARIA attributes (escape hatch for uncommon attributes).

Trait Implementations

impl<'a> Clone for SemanticNode<'a>

fn clone(&self) -> SemanticNode<'a>

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<'a> Follow<'a> for SemanticNode<'a>

type Inner = SemanticNode<'a>

unsafe fn follow(buf: &'a [u8], loc: usize) -> Self::Inner

Safety

impl<'a> PartialEq for SemanticNode<'a>

fn eq(&self, other: &SemanticNode<'a>) -> 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 Verifiable for SemanticNode<'_>

fn run_verifier( v: &mut Verifier<'_, '_>, pos: usize, ) -> Result<(), InvalidFlatbuffer>

Runs the verifier for this type, assuming its at position pos in the verifier’s buffer. Should not need to be called directly.
