Trait RFromStr 

pub trait RFromStr: Sized {
    // Required method
    fn r_from_str(s: &str) -> Option<Self>;
}

Adapter trait for std::str::FromStr.

Provides string parsing for R, allowing R strings to be parsed into Rust types. Automatically implemented for any type that implements FromStr.

Methods

• r_from_str(s: &str) (from_str() in R) - Parse a string into this type, returning None on failure

Example

use std::net::IpAddr;

// IpAddr implements FromStr
#[derive(ExternalPtr)]
struct IpAddress(IpAddr);

#[miniextendr]
impl miniextendr_api::adapter_traits::RFromStr for IpAddress {}

In R:

ip <- IpAddress$RFromStr$from_str("192.168.1.1")

Required Methods

fn r_from_str(s: &str) -> Option<Self>

Parse a string into this type.

Returns Some(value) on success, None on parse failure, which R receives as NULL.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
