trustfall_stubgen
Given a Trustfall schema, autogenerate a high-quality Rust adapter stub fully wired up with all types, properties, and edges referenced in the schema.
First, install the CLI with: cargo install --locked trustfall_stubgen
Then generate Trustfall adapter stubs for your schema with:
trustfall_stubgen --schema <your_schema.graphql> --target <output_directory>
Under the hood this directly calls the generate_rust_stub() function from this crate.
This crate can also be used as a library, so you can call that function directly from
your own code without going through the CLI.
The generated Trustfall adapter stub has the following structure:
| file name | purpose |
|---|---|
| adapter/mod.rs | connects everything together |
| adapter/schema.graphql | contains the schema for the adapter |
| adapter/adapter.rs | contains the adapter implementation |
| adapter/vertex.rs | contains the vertex type definition |
| adapter/entrypoints.rs | contains the entry points where all queries must start |
| adapter/properties.rs | contains the property implementations |
| adapter/edges.rs | contains the edge implementations |
| adapter/tests.rs | contains test code |
See an example of a generated adapter stub from this crate's test suite.
