A validator that raises a `TypeError` if the initializer is called
with a wrong type for this particular attribute (checks are performed using
`isinstance` therefore it's also valid to pass a tuple of types).
:param type: The type to check for.
:type type: type or tuple of types
:raises TypeError: With a human readable error message, the attribute
(of type `attr.Attribute`), the expected type, and the value it
got.

A validator that raises `ValueError` if the initializer is called
with a string that doesn't match *regex*.
:param str regex: a regex string to match against
:param int flags: flags that will be passed to the underlying re function
(default 0)
:param callable func: which underlying `re` function to call (options
are `re.fullmatch`, `re.search`, `re.match`, default
is ``None`` which means either `re.fullmatch` or an emulation of
it on Python 2). For performance reasons, they won't be used directly
but on a pre-`re.compile`\ ed pattern.

which can be set to ``None`` in addition to satisfying the requirements of
the sub-validator.
