| ``KeysValidator`` | |
| ================= | |
| .. class:: KeysValidator(keys, strict=False, messages=None) | |
| Validates that the given keys are contained in the value. If ``strict`` is | |
| ``True``, then it also checks that there are no other keys present. | |
| The ``messages`` passed should be a dict containing the keys | |
| ``missing_keys`` and/or ``extra_keys``. | |
| .. note:: | |
| Note that this checks only for the existence of a given key, not that | |
| the value of a key is non-empty. | |

| ``RangeMinValueValidator`` | |
| -------------------------- | |
| .. class:: RangeMinValueValidator(limit_value, message=None) | |
| Validates that the lower bound of the range is not less than the | |
| ``limit_value``. | |
