Struct measurements::power::Power

pub struct Power { /* fields omitted */ }

The Power struct can be used to deal with energies in a common way. Common metric and imperial units are supported.

Example

use measurements::Power;

let power = Power::from_horsepower(100.0);
let k_w = power.as_kilowatts();
println!("A 100.0 hp car produces {} kW", k_w);
