impl CpuInfo

Struct that allows reading of cpu power info

§Example

    let cpu = CpuInfo::new()?;
    let power = cpu.read()?;

    println!("Package power:");
    for (package, usage) in power.packages().enumerate() {
        println!("\t#{}: {:.2}W", package, usage);
    }
    println!("Core power:");
    for (core, usage) in power.cores().enumerate() {
        println!("\t#{}: {:.2}W", core, usage);
    }

Source

pub fn new() -> Result<Self, Error>
