OGMark - OpenGeometry

class OGMark Make a mark with OpenGeometry.mark(). Do not call the constructor.

import { OpenGeometry, Solid, OG_PRIMITIVE_CUBOID, type OGMark } from 'opengeometry';

await OpenGeometry.create(
  { wasmURL: '/opengeometry_bg.wasm' },
  { workerURL: '/tessellation-worker.js' },
);

const mark: OGMark = OpenGeometry.mark();
new Solid(OG_PRIMITIVE_CUBOID, { width: 1, height: 1, depth: 1 });
mark.rollback();
mark.release();
console.log(OpenGeometry.markStats());

rollback

rollback(): void Takes the document back to the mark. The mark stays live. Marks made after it are released.

release

release(): void Ends the mark and frees the history that only it kept. Both throw InvalidMark on a released mark.

OpenGeometry.markStats() returns { liveMarks, retainedRevisions }.
OpenGeometry.transaction(fn, { dryRun? }) runs fn between a mark and its release, and rolls back if fn throws.
