Implementations

impl CpalBackend

pub fn pop_cpu_usage(&mut self) -> Option<f32>

Returns the oldest reported CPU usage in the queue.

The formula for the CPU usage is time elapsed / time allotted, where

• time elapsed is the amount of time it took to fill the audio buffer requested by the OS
• time allotted is the maximum amount of time Kira could take to process audio and still finish in time to avoid audio stuttering (num frames / sample rate)
