Function psutil::cpu::cpu_percent_percpu

pub fn cpu_percent_percpu(interval: f64) -> Result<Vec<f64>>

Return a vector of floats representing the current system-wide CPU utilization as percentage.

Interval must be > 0.0 seconds. If interval < 0.1, the result of this function will be meaningless. The function compares system CPU times per CPU elapsed before and after the interval (blocking).
