AsFromStr

miniextendr_api::convert

Struct AsFromStr 

Source 
pub struct AsFromStr<T>(pub T);
Expand description

Wrap a parsed T: FromStr from an R character scalar.

Pass an R character scalar and it will be parsed into T via str::parse().

§Example

ⓘ
use std::net::IpAddr;

#[miniextendr]
fn check_ip(addr: AsFromStr<IpAddr>) -> bool {
    addr.0.is_loopback()
}
// R: check_ip("127.0.0.1") → TRUE
