Struct Run 

pub struct Run { /* private fields */ }

Where one editor’s run of edits left off: the kind of the last edit and where it left the caret, which decides whether the next edit joins that step or opens one of its own.

Implementations

impl Run

pub fn joins(&self, kind: EditKind, selection: Selection) -> bool

Whether an edit of kind from selection continues the run — same kind, same text, and picking up exactly where the last one stopped. Structural edits never do.

pub fn landed(&mut self, kind: EditKind, selection: Selection)

Close the edit, noting where it left the caret. The next edit joins this run only if it starts from exactly here.

pub fn interrupt(&mut self)

Anything that is not an edit ends the run — a motion, a click, a focus change. Without this, typing a word, clicking elsewhere and typing again would undo as one step across two places.

Trait Implementations

impl Default for Run

fn default() -> Self

Returns the “default value” for a type.
