Struct AsFromStrVec 

pub struct AsFromStrVec<T>(pub Vec<T>);

Wrap a Vec<T: FromStr> parsed from an R character vector.

Each element of the R character vector is parsed into T. All parse errors are collected with their indices.

Example

use std::net::IpAddr;

#[miniextendr]
fn parse_ips(addrs: AsFromStrVec<IpAddr>) -> Vec<bool> {
    addrs.0.into_iter().map(|ip| ip.is_loopback()).collect()
}
// R: parse_ips(c("127.0.0.1", "8.8.8.8")) → c(TRUE, FALSE)
