# @example
# DocString.new

# attribute. For a DocString model, this will be the content of the
# doc string. If *verbose* is true, provides default Ruby inspection
# behavior instead.
#
# @example
# doc_string.inspect
# doc_string.inspect(verbose: true)
#
# @param verbose [Boolean] Whether or not to return the full details of
# the object. Defaults to false.
# @return [String] A string representation of this model
