Class ​Test​From​DType​Attribute Undocumented
Class ​Test​Metadata Undocumented
Class ​Test​Monster​Type Test deeply nested subtypes.
Class ​Test​Pickling Undocumented
Class ​Test​Promotion Test cases related to more complex DType promotions. Further promotion tests are defined in test_numeric.py
Class ​Test​Record No class docstring; 2/18 methods documented
Class ​Test​String Undocumented
Class ​Test​Structured​Dtype​Sparse​Fields Tests subarray fields which contain sparse dtypes so that not all memory is used by the dtype work. Such dtype's should leave the underlying memory unchanged.
Class ​Test​Structured​Object​Refcounting These tests cover various uses of complicated structured types which include objects and thus require reference counting.
Class ​Test​Subarray No class docstring; 5/11 methods documented

Function iter​_struct​_object​_dtypes Iterates over a few complex dtypes and object pattern which fill the array with a given object (defaults to a singleton).

Undocumented

def assert_dtype_not_equal(a, b):

Undocumented

def iter_struct_object_dtypes():

Iterates over a few complex dtypes and object pattern which fill the array with a given object (defaults to a singleton).

Yields

dtype : dtype pattern : tuple

Structured tuple for use with np.array.
count : int
Number of objects stored in the dtype.
singleton : object
A singleton object. The returned pattern is constructed so that all objects inside the datatype are set to the singleton.
