Overview

extern crate cupid;

fn main() {
    let information = cupid::master();
    println!("{:#?}", information);
    if let Some(information) = information {
        if information.sse4_2() {
             println!("SSE 4.2 Available");
        }
    }
}

Cupid currently requires a Rust nightly build as it makes use of inline assembly. Chances are good that if you want to use the functionality provided, you are also doing some low-level trickery, so hopefully this won't be too inconvenient.
