pub struct State(_);

Implementations

impl State

pub fn current() -> Result<State>

Captures the current state of all CPUs on the system.

The State returned here isn’t too meaningful in terms of interpretation across platforms, but it can be compared to previous states to get a meaningful cross-platform number.

pub fn idle_since(&self, previous: &State) -> f64

Returns the percentage of time CPUs were idle from the current state relative to the previous state, as a percentage from 0.0 to 100.0.

This function will return, as a percentage, the amount of time that the entire system was idle between the previous state and this own state. This can be useful to compare two snapshots in time of CPU usage to see how the CPU usage compares between the two.
