Function num_members

src/thread_pool.rs:2496–2501

Returns the number of members participating in a thread-pool. When executed on a thread that is currently registered as a worker (i.e. the closure inside [`Membership::activate`], [`ThreadPool::with_worker`], or similar) this is able to look up that registration and find the worker and thread-pool implicitly. If not called within a thread pool, this uses the [`DEFAULT_POOL`].

            //   The `op` is `Send`, so this does not apply.
            //
            // * The function `op` must not unwind.
            //
            //   `op` catches panics from the broadcast operation and passes
            //   them to `ThreadPool::handle_panic`, which never unwinds.
