Struct AsList 

pub struct AsList<T: IntoList>(pub T);

Wrap a value and convert it to an R list via IntoList when returned from Rust.

Use this wrapper when you want to convert a single value to an R list without making that the default behavior for the type.

Example

#[derive(IntoList)]
struct Point { x: f64, y: f64 }

#[miniextendr]
fn make_point() -> AsList<Point> {
    AsList(Point { x: 1.0, y: 2.0 })
}
// In R: make_point() returns list(x = 1.0, y = 2.0)
