[−][src]Function rayon_logs::current_num_threads
pub fn current_num_threads() -> usize
We re-export rayon's current_num_threads
.
Returns the number of threads in the current registry. If this
code is executing within a Rayon thread-pool, then this will be
the number of threads for the thread-pool of the current
thread. Otherwise, it will be the number of threads for the global
thread-pool.
This can be useful when trying to judge how many times to split parallel work (the parallel iterator traits use this value internally for this purpose).
Future compatibility note
Note that unless this thread-pool was created with a
builder that specifies the number of threads, then this
number may vary over time in future versions (see the
num_threads()
method for details).
