Geomerge Demo

This demo shows how to store and read data from Geomerge.

The demo:

1. loads the compiled paths.json schema,
2. creates a Geomerge store,
3. inserts a small graph dataset in one transaction,
4. reads the inserted edge back,
5. persists the store to bytes,
6. reloads it, and checks that the restored store matches the original.

The SVG is generated from docs/diagrams/workflow.dot. To regenerate it after editing the .dot source, run:

bash docs/diagrams/make_figures.sh docs/diagrams

Run

cargo run -p geomerge-demo

Expected output includes table and law counts, row counts for graphs, vertices, and edges, edge endpoints, and persisted byte size.

Test

cargo test -p geomerge-demo

The tests cover the successful store, read, and persistence round trip, plus a rejected invalid edge insert that must leave the store unchanged.
