Options#

The usage of options is explained in the user guide. This document provides more explanations on how developers work with options internally.

Options are stored as a dictionary in the cudf.options module. Each option name is its key in the dictionary. The value of the option is an instance of an Options object.

An Options object has the following attributes:

  • value: the current value of the option

  • description: a text description of the option

  • validator: a boolean function that returns True if value is valid, False otherwise.

Developers can use cudf.options._register_option to add options to the dictionary. cudf.get_option() is provided to get option values from the dictionary.

When testing the behavior of a certain option, it is advised to use yield fixture to set up and clean up the option.

See the API reference for more details.
