Validators
==========

All validators accept a value via their ``validate()`` method.
On success they return the validated (possibly coerced) value.
On failure they raise :class:`~valify.exceptions.ValidationError`.

StringValidator
---------------

.. autoclass:: valify.validators.StringValidator
   :members:
   :show-inheritance:

IntValidator
------------

.. autoclass:: valify.validators.IntValidator
   :members:
   :show-inheritance:

FloatValidator
--------------

.. autoclass:: valify.validators.FloatValidator
   :members:
   :show-inheritance:

BoolValidator
-------------

.. autoclass:: valify.validators.BoolValidator
   :members:
   :show-inheritance:

EmailValidator
--------------

.. autoclass:: valify.validators.EmailValidator
   :members:
   :show-inheritance:

OptionalValidator
-----------------

.. autoclass:: valify.validators.OptionalValidator
   :members:
   :show-inheritance:

ListValidator
-------------

.. autoclass:: valify.validators.ListValidator
   :members:
   :show-inheritance:

EnumValidator
-------------

.. autoclass:: valify.validators.EnumValidator
   :members:
   :show-inheritance:

JSON Schema Export
------------------

All validators support exporting themselves to JSON Schema via
:meth:`~valify.validators.Validator.to_json_schema`.

Example::

    from valify import StringValidator

    validator = StringValidator(
        min_length=2,
        max_length=50,
    )

    print(validator.to_json_schema())

Output::

    {
        "type": "string",
        "minLength": 2,
        "maxLength": 50
    }

JSON Schema export enables integration with:

* OpenAPI
* FastAPI
* Form generators
* Documentation systems
* Other JSON Schema compatible tools
