Struct Snapshot

Source

pub struct Snapshot {
    pub rope: Rope,
    pub selections: Selections,
}

Expand description

The buffer as it stood before an edit, and where the cursors were.

Storing the selections is what makes undo put the caret back where the edit happened rather than wherever clamping left it. Every editor in the field does this; an undo that leaves the cursor somewhere unrelated is disorienting enough that users stop trusting it.
