Examples

To parse HelloWorld.scilla contract:

    use scilla_parser::{Contract, Field, FieldList, Transition, TransitionList, Type};

    let contract_path = PathBuf::from("tests/contracts/HelloWorld.scilla");
    let contract = Contract::parse(&contract_path).unwrap();

    assert_eq!(
        contract,
        Contract {
            name: "HelloWorld".to_string(),
            init_params: FieldList(vec![Field::new("owner", Type::ByStr(20))]),
            fields: FieldList(vec![Field::new("welcome_msg", Type::String)]),
            transitions: TransitionList(vec![
                Transition::new("setHello", FieldList(vec![Field::new("msg", Type::String)])),
                Transition::new_without_param("getHello")
            ])
        }
    );
