kandi X-RAY | rust-scoped-pool Summary
Example of simple use (applying a transformation to every item in an array):. Besides the core API used above (Pool::new, Pool::scoped) this crate also provides many extremely useful convenience functions for complex code using scoped threads. Also includes the raw WaitGroup type, which can be used to implement similar "wait for a group of actions to complete" logic, and is used in Pool and Scope. See the generated documentation (linked above) for details.

QUESTION
I have a tree structure in Rust which I would like to process in parallel. My real problem is more complicated, but this is essentially the serial version I have now:
...ANSWER
Answered 2017-Mar-18 at 21:18in a deadlock, and I don't understand why
You have 4 threads, then call map_parallel
once, which ties up a thread, which calls map_parallel
itself before it exits, which ties up a thread, and so on. You ran out of threads before any thread could finish. Switching to 5 threads "fixes" the deadlock in this example. Obviously, switching the number of threads depending on the depth of the tree is not ideal.
I'd recommend splitting up your code into separate concerns. Since you are already handling things in parallel, each node needs to be independent from each other. That means you can implement an iterator:
