Nested struct with from_item_all

[andronat]

I would like to parse a python dictionary to the following nested rust structs:

#[derive(FromPyObject, Debug, Default, Clone)]
#[pyo3(from_item_all)]
pub struct Top {
    pub a_vec: Vec<String>,
    pub nested: Option<Nested>,
}

#[derive(FromPyObject, Debug, Clone, Default)]
#[pyo3(from_item_all)]
pub struct Nested {
    pub f1: Option<bool>,
    pub f2: Option<bool>,
}

by using .extract::<Top>().

I'm currently getting this error:

Error: TypeError: failed to extract field Top.nested

Am I doing something wrong? Or nested structs are not supported?

In my internal example which is much more complex, I was missing #[pyo3(from_item_all)] from all nested structs.
