Macro numpy::pyarray

macro_rules! pyarray {
    ($py : ident, $([$([$($x : expr), * $(,) *]), + $(,) *]), + $(,) *) => { ... };
    ($py : ident, $([$($x : expr), * $(,) *]), + $(,) *) => { ... };
    ($py : ident, $($x : expr), * $(,) *) => { ... };
}

Create a PyArray with one, two or three dimensions. This macro is backed by ndarray::array.

Example

pyo3::Python::with_gil(|py| {
    let array = numpy::pyarray![py, [1, 2], [3, 4]];
    assert_eq!(
        array.readonly().as_array(),
        ndarray::array![[1, 2], [3, 4]]
    );
});
