struct UndoStack

Swift

struct UndoStack

Undo/redo history for a single buffer.

Coalescing is deliberately time-free. A timer makes the split points depend on how fast someone types, which is both untestable and surprising ("why did that undo only half a word?"). Instead a run breaks on a word boundary, a direction change, or anything that is not a simple continuation — deterministic, and it matches where a user thinks a word ended.
