BareValidatora
Validator class. Normalizes and/or validates any mapping against a
validation-schema which is provided as an argument at class instantiation
or upon calling the :meth:`~cerberus.Validator.validate`,
:meth:`~cerberus.Validator.validated` or
:meth:`~cerberus.Validator.normalized` method. An instance itself is
callable and executes a validation.
All instantiation parameters are optional.
There are the introspective properties :attr:`types`, :attr:`validators`,
:attr:`coercers`, :attr:`default_setters`, :attr:`rules`,
:attr:`normalization_rules` and :attr:`validation_rules`.
The attributes reflecting the available rules are assembled considering
constraints that are defined in the docstrings of rules' methods and is
effectively used as validation schema for :attr:`schema`.
:param schema: See :attr:`~cerberus.Validator.schema`.
Defaults to :obj:`None`.
:type schema: any :term:`mapping`
:param ignore_none_values: See :attr:`~cerberus.Validator.ignore_none_values`.
Defaults to ``False``.
:type ignore_none_values: :class:`bool`
:param allow_unknown: See :attr:`~cerberus.Validator.allow_unknown`.
Defaults to ``False``.
:type allow_unknown: :class:`bool` or any :term:`mapping`
:param require_all: See :attr:`~cerberus.Validator.require_all`.
Defaults to ``False``.
:type require_all: :class:`bool`
:param purge_unknown: See :attr:`~cerberus.Validator.purge_unknown`.
Defaults to to ``False``.
:type purge_unknown: :class:`bool`
:param purge_readonly: Removes all fields that are defined as ``readonly`` in the
normalization phase.
:type purge_readonly: :class:`bool`
:param error_handler: The error handler that formats the result of
:attr:`~cerberus.Validator.errors`.
When given as two-value tuple with an error-handler
class and a dictionary, the latter is passed to the
initialization of the error handler.
Default: :class:`~cerberus.errors.BasicErrorHandler`.
:type error_handler: class or instance based on
:class:`~cerberus.errors.BaseErrorHandler` or
:class:`tuple`

Creates and adds one or multiple errors.
:param args: Accepts different argument's signatures.
*1. Bulk addition of errors:*
- :term:`iterable` of
:class:`~cerberus.errors.ValidationError`-instances
The errors will be added to
:attr:`~cerberus.Validator._errors`.
*2. Custom error:*
- the invalid field's name
- the error message
A custom error containing the message will be created and
added to :attr:`~cerberus.Validator._errors`.
There will however be fewer information contained in the
error (no reference to the violated rule and its
constraint).
*3. Defined error:*
- the invalid field's name
- the error-reference, see :mod:`cerberus.errors`
- arbitrary, supplemental information about the error
A :class:`~cerberus.errors.ValidationError` instance will
be created and added to
:attr:`~cerberus.Validator._errors`.

Searches for a field as defined by path. This method is used by the
``dependency`` evaluation logic.
:param path: Path elements are separated by a ``.``. A leading ``^``
indicates that the path relates to the document root,
otherwise it relates to the currently evaluated document,
which is possibly a subdocument.
The sequence ``^^`` at the start will be interpreted as a
literal ``^``.
:type path: :class:`str`
:returns: Either the found field name and its value or :obj:`None` for
both.
:rtype: A two-value :class:`tuple`.

Returns the document normalized according to the specified rules of a schema.
:param document: The document to normalize.
:type document: any :term:`mapping`
:param schema: The validation schema. Defaults to :obj:`None`. If not
provided here, the schema must have been provided at
class instantiation.
:type schema: any :term:`mapping`
:param always_return_document: Return the document, even if an error
occurred. Defaults to: ``False``.
:type always_return_document: :class:`bool`
:return: A normalized copy of the provided mapping or :obj:`None` if an
error occurred during normalization.
