source§impl State
impl State
sourcepub fn current() -> Result<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.
sourcepub fn idle_since(&self, previous: &State) -> f64
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.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
