How do you dynamically change the number of threads at runtime?
There's no way to do that in the global pool, but you can create an independent pool with build()
instead of build_global()
, and give that a different number of threads. Save that to a name like pool
, then you can pool.install(|| ...)
to run code in there.
Changing the number of threads at runtime segment faults.
Hopefully not! I suspect you mean that it panics when your unwrap()
encounters a Result::Err
from attempting to build the global pool twice. That's normal, but you can also add more graceful handling of that error, whatever makes sense in your situation.

Thanks for the help
Threadpool .build() and .install() worked for me
from rayon.
