Public Functions

inline std::size_t ndim() const noexcept

Retrieve number of array dimensions.

inline std::size_t size() const noexcept

Retrieve array size.

inline const std::vector<std::size_t> &shape() const noexcept

Retrieve array shape.

inline nb::tuple python_get_shape() const

Retrieve array shape (exported to Python)

Protected Functions

inline APyBuffer(const std::vector<std::size_t> &shape, std::size_t itemsize = 1)

APyBuffers are to be inherited from. All fields and constructors are protected.

Base constructor for creating a new APyBuffer

inline APyBuffer(const std::vector<std::size_t> &shape, std::size_t itemsize, vector_type &&v)

Base constructor for creating new APyBuffer stealing data from another vector.

inline Py_buffer get_py_buffer()

Return a Python Buffer structure compatible with the Buffer Protocol.

inline void buffer_resize(const std::vector<std::size_t> shape, std::size_t itemsize)

Resize the underlying buffer without touching its data. Narrowing the buffer will result in loss of data.
