Commits on Nov 16, 2022

  1. Add ThreadPool::broadcast 

    A broadcast runs the closure on every thread in the pool, then collects
the results.  It's scheduled somewhat like a very soft interrupt -- it
won't preempt a thread's local work, but will run before it goes to
steal from any other threads.

This can be used when you want to precisely split your work per-thread,
or to set or retrieve some thread-local data in the pool, e.g. rayon-rs#483.
