Source

pub fn new(name: impl Into<String>) -> Self

Start recording a new macro with the given name.

Source

Record an action (appended to the end). Does nothing if the recorder has been finished.

Source

pub fn action_count(&self) -> usize

How many actions have been recorded so far.

Source

pub fn is_recording(&self) -> bool

Whether the recorder is still accepting actions.

Source

pub fn undo_last(&mut self) -> Option<MacroAction>

Returns the removed action, or None if empty or not recording.

Source

pub fn finish(self) -> Macro

Finish recording and produce the Macro.

After this call the recorder is consumed.
