Struct EditController 

pub struct EditController(/* private fields */);

Implementations

impl EditController

pub fn new() -> Self

pub fn id(&self) -> u64

Unique id — how the engine finds the render-tree node that declared this controller (same shape as FocusNode::id).

pub fn replace_range(&self, start: usize, end: usize, text: impl Into<String>)

Replace an explicit [start, end) char range — independent of wherever the caret currently is (the markdown-toolbar-Bold-button primitive: replace_range(sel.0, sel.1, format!("**{}**", text))).

pub fn insert_at_cursor(&self, text: impl Into<String>)

pub fn set_selection(&self, sel: Selection)

pub fn select_all(&self)

pub fn undo(&self)

pub fn redo(&self)

pub fn value(&self) -> String

The field’s value as of the last time the engine applied a drained op (a read-only snapshot — not live within the same frame an op was JUST enqueued; the engine hasn’t run yet).

pub fn selection(&self) -> Selection
