rust-cpuid

crates.io Build Status Coverage Status

Rust bindings for libpcuid CPU detection and feature extraction library.

Usage

First - download, and build libcpuid as described in the readme. Install it by running make install (you may want to run ldconfig afterwards).

Add to your Cargo.toml:

[dependencies]
cpuid = "*"

Add extern crate cpuid to your crate root and you're good to go! For example:

extern crate cpuid;

fn main () {
    match cpuid::identify() {
        Ok(info) => {
            println!("Found: {} CPU, model: {}", info.vendor, info.codename);
            println!("The full brand string is: {}", info.brand);
            println!("Hardware AES support: {}", if info.has_feature(cpuid::CpuFeature::AES) { "yes" } else { "no" });
        },
        Err(err) => println!("cpuid error: {}", err),
    };
    match cpuid::clock_frequency() {
        Some(frequency) => println!("CPU speed: {} MHz", frequency),
        None => println!("Couldn't get CPU speed."),
    };
}
