Inheritance diagram for dtype:

Public Member Functions
	dtype (const buffer_info &info)
	dtype (const std::string &format)
	dtype (const char *format)
	dtype (list names, list formats, list offsets, ssize_t itemsize)
bool	has_fields () const
	Returns true for structured data types. More...
ssize_t	itemsize () const
	Size of the data type in bytes. More...
char	kind () const
	Single-character type code. More...
	PYBIND11_OBJECT_DEFAULT (dtype, object, detail::npy_api::get().PyArrayDescr_Check_)
Public Member Functions inherited from object
template<typename T >
T	cast () const &
template<typename T >
T	cast ()&&
template<>
void	cast () const &
template<>
void	cast ()&&
	object ()=default
	object (const object &o)
	Copy constructor; always increases the reference count. More...
	object (object &&other) noexcept
	Move constructor; steals the object from other and preserves its reference count. More...
	object (handle h, borrowed_t)
	object (handle h, stolen_t)
object &	operator= (const object &other)
object &	operator= (object &&other) noexcept
	PYBIND11_DEPRECATED ("Use reinterpret_borrow<object>() or reinterpret_steal<object>()") object(handle h
handle	release ()
	~object ()
	Destructor; automatically calls handle::dec_ref() More...
Public Member Functions inherited from handle
template<typename T >
T	cast () const
template<>
void	cast () const
bool	check () const
const handle &	dec_ref () const &
	handle ()=default
	The default constructor creates a handle with a nullptr-valued pointer. More...
	handle (PyObject *ptr)
	Creates a handle from the given raw Python object pointer. More...
const handle &	inc_ref () const &
	operator bool () const
	Return true when the handle wraps a valid Python object. More...
bool	operator!= (const handle &h) const
bool	operator== (const handle &h) const
PyObject *	ptr () const
	Return the underlying PyObject * pointer. More...
PyObject *&	ptr ()

Static Public Member Functions
static dtype	from_args (object args)
	This is essentially the same as calling numpy.dtype(args) in Python. More...
template<typename T >
static dtype	of ()
	Return dtype associated with a C++ type. More...

Private Member Functions
dtype	strip_padding (ssize_t itemsize)

Static Private Member Functions
static object	_dtype_from_pep3118 ()

Additional Inherited Members
Public Attributes inherited from object
bool	is_borrowed: handle(h) { if (is_borrowed) inc_ref()
Protected Attributes inherited from handle
