def is_unsigned_integer_dtype(arr_or_dtype):
return _is_dtype_type(<EOL>arr_or_dtype, classes_and_not_datetimelike(np.unsignedinteger))<EOL>
Check whether the provided array or dtype is of an unsigned integer dtype.

.. versionchanged:: 0.24.0

   The nullable Integer dtypes (e.g. pandas.UInt64Dtype) are also
   considered as integer by this function.

Parameters
----------
arr_or_dtype : array-like
    The array or dtype to check.

Returns
-------
boolean
    Whether or not the array or dtype is of an unsigned integer dtype.

Examples
--------
>>> is_unsigned_integer_dtype(str)
False
>>> is_unsigned_integer_dtype(int)  # signed
False
>>> is_unsigned_integer_dtype(float)
False
>>> is_unsigned_integer_dtype(np.uint64)
True
>>> is_unsigned_integer_dtype('uint8')
True
>>> is_unsigned_integer_dtype('UInt8')
True
>>> is_unsigned_integer_dtype(pd.UInt8Dtype)
True
>>> is_unsigned_integer_dtype(np.array(['a', 'b']))
False
>>> is_unsigned_integer_dtype(pd.Series([1, 2]))  # signed
False
>>> is_unsigned_integer_dtype(pd.Index([1, 2.]))  # float
False
>>> is_unsigned_integer_dtype(np.array([1, 2], dtype=np.uint32))
True
