array_t

Fully qualified name: wp::array_t

template<typename T>
struct array_t

Binary-compatible view of a Python wp.array of element type T.

Layout matches wp::array_t<T> in the native Warp runtime: T* data, T* grad, :class:shape_t shape, int strides[4], int ndim. Strides are byte strides. grad is null when the array has no gradient.

Public Functions

inline array_t()

inline array_t(T *data, int size, T *grad = nullptr)

Constructs a one-dimensional array view over an existing buffer.

Parameters:

• data – [in] Pointer to the first element of the buffer.

• size – [in] Number of elements in the buffer.

• grad – [in] Optional pointer to the gradient buffer, or nullptr if none.

inline bool empty() const

Returns whether the array has no backing data.

Returns:

True if the data pointer is null; false otherwise.

inline operator T*() const

Implicitly converts the array view to a pointer to its underlying data.

Returns:

Pointer to the first element of the array data.

Public Members

T *data

Pointer to the first element of the array data.

T *grad

Pointer to the gradient buffer, or null when the array has no gradient.

shape_t shape

Per-dimension element counts of the array.

int strides[ARRAY_MAX_DIMS]

Per-dimension byte strides between consecutive elements.

int ndim

Number of valid dimensions in the array.
