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 --features cli 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 |

See an example of a generated adapter stub from this crate's test suite.
