Struct DoUndoActions 

pub struct DoUndoActions { /* private fields */ }

A command backed by two closures: one for do_it and one for undo_it.

This is the Rust equivalent of the C# DoUndoActions class. Use it for simple operations where capturing state in closures is natural.

For operations that share state with an owning object (e.g. text editing), consider using std::rc::Rc<std::cell::RefCell<T>> to share mutable state between the owning widget and the undo command closures.

impl DoUndoActions

pub fn new( name: impl Into<String>, do_action: impl FnMut() + 'static, undo_action: impl FnMut() + 'static, ) -> Self

Create a command with the given name, do_action, and undo_action.
