Trait RDefault 

pub trait RDefault {
    // Required method
    fn r_default() -> Self;

#[derive(Default, ExternalPtr)]
struct Config {
    timeout: u32,     // defaults to 0

    verbose: bool,    // defaults to false
}

#[miniextendr]
impl miniextendr_api::adapter_traits::RDefault for Config {}

In R:

config <- Config$RDefault$default()  # All fields have default values
