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: mod.rs
    path of file: ./repos/xsd-parser-rs/xsd-parser/src/generator
    
    the code of the file until where you have to start completion: pub mod alias;
pub mod base;
pub mod builder;
pub mod default;
pub mod r#enum;
pub mod enum_case;
pub mod import;
pub mod r#struct;
pub mod struct_field;
pub mod tuple_struct;
mod utils;
pub mod
    
    fn test_generate_rs_file() {
        let gen = GeneratorBuilder::default().build();
        let mut rs_file = RsFile::default();
        assert!(gen.generate_rs_file(&rs_file).is_empty());

        rs_file.types.push(RsEntity::TupleStruct(TupleStruct {
            name: "name".to_string(),
            comment: Some("comment".into()),
            type_name: "type".to_string(),
            ..Default::default()
        }));
        let comment = "// comment\n";
        let macros = "#[derive(Default, PartialEq, Debug, UtilsTupleIo, UtilsDefaultSerde)]\n";
        let validation = "impl Validate for Name {}\n";
        let expected = format!(
            "{}{}pub struct Name (pub Type);\n\n{}",
            comment, macros, validation
        );
        assert_eq!(gen.generate_rs_file(&rs_file), expected);
    }
