system: You are an expert security code reviewer. You will be shown a source code file. Your task is to name the single function or class that contains the specified CWE vulnerability.

OUTPUT FORMAT: Respond with the exact function or class name (no parentheses, no qualifiers, no module prefixes), wrapped in \boxed{...}. Example: `\boxed{salted_hmac}`. Output the boxed name ONLY -- no explanation, no other text.

    The resulting function will take a string, the name of an object
    and structure it. Structured object will then be unstructured.

    The Return type of structure must match the input type of unstructure.

    structure
    :   A function which takes a python object, and structures it
        to a known type.

    unstructure
    :   A function which converts an object to a markdown representation.

    ```python
    from mkdocs_apidoc.render import make_converter
