pub fn max_threads() -> Result<(usize, usize)>Expand description
Returns the soft and hard per-user process-count limits.
The tuple is ordered as the current soft limit followed by the maximum hard
limit. Values come from RLIMIT_NPROC; on Linux, it counts extant threads
for the caller’s real user ID.
§Panics
Panics when either platform limit cannot be represented as usize.
