Returning multiple values ?

[nyue]

I have a Rust function that looks like this

pub fn uv_sphere(n_stacks: u32, n_slices: u32) -> (Vec<u32>, Vec<u32>, Vec<rust_3d::Point3D>)

How do I use PyResult to return it when using pyo3 ?

Cheers

I ended with

#[pyfunction]
pub fn uv_sphere(n_stacks: u32, n_slices: u32, py: Python) -> &PyDict {

and returning via

    let items = vec![
        ("fverts".to_object(py), f_vertex_indices.to_object(py)),
        ("nverts".to_object(py), nverts.to_object(py)),
        ("verts".to_object(py), verts.to_object(py))
    ].to_object(py);

    PyDict::from_sequence(py, items).unwrap()

You should also be able to just wrap the tuple in PyResult, e.g.

pub fn uv_sphere(n_stacks: u32, n_slices: u32) -> PyResult<(Vec<u32>, Vec<u32>, Vec<rust_3d::Point3D>)>;

which is produced as

Ok((f_vertex_indices, nverts, verts))
