pub struct CpuDelta { /* private fields */ }
Expand description

The amount of CPU time between thread samples.

This is used in the Firefox Profiler UI to draw an activity graph per thread.

A thread only runs on one CPU at any time, and can get scheduled off and on the CPU between two samples. The CPU delta is the accumulation of time it was running on the CPU.
