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: db_util.rs
    path of file: ./repos/readyset/replicators/src
    
    the code of the file until where you have to start completion: //! Database Utilities
//! Contains helpers for determining the schemas and tables of a database for use in replication

        anonymizer.replace(&mut name);
        assert_eq!(SqlIdentifier::from("anon_id_0"), name);

        // A second run with the same input produces the same mapping
        let mut name = SqlIdentifier::from("table1");
        anonymizer.replace(&mut name);
        assert_eq!(SqlIdentifier::from("anon_id_0"), name);

        // But another input produces the next output
        let mut name = SqlIdentifier::from("table2");
        anonymizer.replace(&mut name);
        assert_eq!(SqlIdentifier::from("anon_id_1"), name);
