Time Travel

All three methods return a Delta describing what changed when the cursor moved.

seekTo(snapshot)

Moves the cursor to any snapshot — forward or backward. This is the general-purpose alternative to calling advance() or rewind() directly when you don't know the direction.

const delta = graph.seekTo(5);

advance(snapshot)

Moves the cursor forward. Throws if snapshot is before the current cursor position.

const delta = graph.advance(10);

rewind(snapshot)

Moves the cursor backward by undoing entries in reverse order. Throws if snapshot is after the current cursor position.

const delta = graph.rewind(3);
console.log(delta.edges.updated); // edges that were rolled back
