You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: crud_status.rs
    path of file: ./repos/holochain-rust/crates/core_types/src
    
    the code of the file until where you have to start completion: //! This module holds the relevant constants and an enum required for Holochain to have 'status' metadata for entries.
//! Since Holochain uses an append-only data structure, but still wishes to pr
    
    fn crud_status_example_eav() {
        let entity_content = ExampleAddressableContent::try_from_content(&JsonString::from(
            RawString::from("example"),
        ))
        .unwrap();
        let attribute = Attribute::LinkTag("favourite-badge".into(), "some-tag".into());
        let value_content: Content =
            CrudStatus::try_from_content(&JsonString::from(CrudStatus::Rejected))
                .unwrap()
                .content();
        eav_round_trip_test_runner(entity_content, attribute, value_content);
    }
