        ## raise_compiler_error

        The `exceptions.raise_compiler_error` method will raise a compiler
        error with the provided message. This is typically only useful in
        macros or materializations when invalid arguments are provided by the
        calling model. Note that throwing an exception will cause a model to
        fail, so please use this variable with care!

        Example usage:

        > exceptions.sql:

            {% if number < 0 or number > 100 %}
              {{ exceptions.raise_compiler_error("Invalid `number`. Got: " ~ number) }}
            {% endif %}

        ## warn

        The `exceptions.warn` method will raise a compiler warning with the
        provided message. If the `--warn-error` flag is provided to dbt, then
        this warning will be elevated to an exception, which is raised.

        Example usage:

        > warn.sql:

            {% if number < 0 or number > 100 %}
              {% do exceptions.warn("Invalid `number`. Got: " ~ number) %}
            {% endif %}
        """  # noqa
