Struct AsDisplay 

pub struct AsDisplay<T>(pub T);

Wrap a T: Display and convert it to an R character scalar.

Any type implementing std::fmt::Display can be returned to R as a string without implementing miniextendr traits.

Example

use std::net::IpAddr;

#[miniextendr]
fn format_ip(ip: &str) -> AsDisplay<IpAddr> {
    AsDisplay(ip.parse().unwrap())
}
// R gets: "192.168.1.1"
