Class Hierarchy

This Rust scaffold project has been automatically generated by Arachne, a code generator from Ecore metamodels to a composition of replicated data types.

Class Hierarchy is a simplified metamodel of a metalanguage, close to Ecore. It features concepts such as class, attribute, datatype, package, and reference.

Generated Artifacts

Arachne generated the classifier.rs, references.rs, package.rs, and lib.rs files.

• classifier.rs: contains the replicated object hierarchy, i.e., the CRDTs reproducing the (concrete and abstract) classes, interfaces, enums, and owned features (attributes and containment references).
• references.rs: contains the Typed Graph CRDT implementation. Manages the non-containment references between replicated objects.
• package.rs: the root replicated object that contains both the object hierarchy and the typed graph. This is the object with which end-users interact.

Running the project

Rust must be installed on your machine: https://rust-lang.org/tools/install. You must have this project, PureOpLib, and Arachne in the same root folder. You can change the path of these dependencies in Cargo.toml. Replace XXXX-1 by the name of PureOpLib.

Running all the tests:

RUST_LOG=debug cargo test

Running the fuzzer:

RUST_LOG=debug cargo test --release -- --ignored --no-capture fuzz
