Trait CommittedActions 

pub trait CommittedActions {
    // Required method
    fn take_committed_action(&mut self) -> Option<Vec<ChangeHash>>;

    // Provided method
    fn keeps_undo_step_open(&self) -> bool { ... }
}

A widget whose own controls dispatch the actions its resource exports, and so report the undo boundary around them (see record_dispatched_action).

Required Methods

fn take_committed_action(&mut self) -> Option<Vec<ChangeHash>>

The document heads captured just before the widget’s last dispatched action. Rising-edge: reading clears it.

Provided Methods

fn keeps_undo_step_open(&self) -> bool

Whether the undo step the last boundary opened stays open for the actions that continue it (the rest of a word typed a keystroke at a time). Answered by the widget itself, never its children.
