Struct TextAnnotationSpan 

pub struct TextAnnotationSpan {
    pub start: usize,
    pub end: usize,
    pub group_id: u64,
    pub summary: String,
}

The main rich text widget. Construct via RichTextEditor::read_only (view/select only) or RichTextEditor::editor (full editing). One annotation (a comment thread) covering [start, end) of the document, in document-absolute character offsets — the space cursors and FindMatch speak.

The framework stays ignorant of what an annotation is: the host supplies already-resolved spans and the text to announce, and this only turns them into AccessKit nodes. That keeps a comment feature’s anchoring rules — which are application policy — out of the widget.

Fields

start: usize

end: usize

group_id: u64

Durable identity of the annotation, so its synthetic NodeId is stable across rebuilds and a screen reader’s cursor is not thrown out of the thread by an unrelated edit elsewhere.

summary: String

What a screen reader should read: author, body, reply count, state.

Trait Implementations

impl Clone for TextAnnotationSpan

fn clone(&self) -> TextAnnotationSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextAnnotationSpan

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

Formats the value using the given formatter.

impl Default for TextAnnotationSpan

fn default() -> TextAnnotationSpan

Returns the “default value” for a type.

impl Eq for TextAnnotationSpan

impl PartialEq for TextAnnotationSpan

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