Unfortunately there's a rustfmt failure. See our CONTRIBUTING file for the appropriate commands to run rustfmt in our repository. |
`steal_count` claimed to be tracking the amount of times a worker successfully stole tasks, but instead tracked the number of tasks stolen. Multiple tasks can be stolen at once. Add the new `steal_operations` metric to be able to track how many times tasks where stolen. Tracking both metrics allows us to better gauge effects of different stealing policies on the work stealing.

Motivation
The documentation of
steal_countdoes not match what is actually counted.Solution
Fix the documentation of
steal_count.Additionally, add
steal_operationsas a metric to track whatsteal_countwas originally documented to count.Having both metrics allows us to see some effects of different stealing policies on work-stealing.
Closes #5281
