pub fn adjust_thread_pool() -> &'static Result<(), ThreadPoolBuildError>Expand description
In case when number of threads is set to 1, use rayon thread pool with
use_current_thread set to true. This is solves two problems:
- The performance is almost the same as if rayon wasn’t used at all
- Makes profiling and debugging results less noisy
NOTE: rayon doesn’t allow initializing global thread pool several times, so
in case when it was initialized before this function returns an error.
The typical usage of the function is to place it’s call in the beginning of the main.
The function returns reference to the result because ThreadPoolBuildError
doesn’t implement Clone.
