    # cloudysanfrancisco@gmail.com becomes XXXXX@gmail.com.
    # * Syntax-invalid email address: Apply SHA-256 hash.

    #
    # Truncation occurs according to the UTC time zone. To change this, adjust
    # the default time zone using the `time_zone` system variable.

#routine ⇒ `::String`

Returns The name of the BigQuery routine that contains the custom masking routine, in the format of projects/{project_number}/datasets/{dataset_id}/routines/{routine_id}.
