pub fn broadcast<OP, R>(op: OP) -> Vec<R>where OP: Fn(BroadcastContext<'_>) -> R + Sync, R: Send,
op within every thread in the current threadpool. If this is
called from a non-Rayon thread, it will execute in the global threadpool.
Any attempts to use
scope, or parallel iterators will then operate
within that threadpool. When the call has completed on each thread, returns
a vector containing all of their return values.
