static get_comparator_from_values(
rules: COMPARE_RULES_TYPE,

  1. (key, old_type, new_type)

  2. key

  3. (old_type, new_type)

  4. old_type or new_type (if one of them is NoneType)

  5. default

Parameters:

  • rules (dict) – Precedence map.

  • default (Compare subclass) – Fallback comparator.

  • key (str) – Field name.

  • old (type) – Types being compared.
