Struct ArrayInterfaceDict 

pub struct ArrayInterfaceDict {
    pub shape: Vec<usize>,
    pub typestr: String,
    pub data_ptr: usize,
    pub readonly: bool,
    pub strides: Option<Vec<usize>>,
    pub version: u8,
}

Data for the __array_interface__ protocol dictionary.

See: https://numpy.org/doc/stable/reference/arrays.interface.html

Fields

shape: Vec<usize>

Logical shape of the array.

typestr: String

NumPy dtype typestr (e.g. "<f8").

data_ptr: usize

Raw pointer to element data, encoded as a Python integer.

readonly: bool

Whether the buffer should be treated as read-only.

strides: Option<Vec<usize>>

Optional per-dimension strides in bytes.

version: u8

Protocol version; always 3.

Implementations

impl ArrayInterfaceDict

pub fn to_py_dict<'py>(&self, py: Python<'py>) -> PyResult<Bound<'py, PyDict>>

Serialize this descriptor into a Python dict suitable for __array_interface__.

The resulting dict has the keys shape, typestr, data, version, and optionally strides.
