Implementations

impl<'a> BroadcastContext<'a>

pub fn index(&self) -> usize

Our index amongst the broadcast threads (ranges from 0..self.num_threads()).

pub fn num_threads(&self) -> usize

The number of threads receiving the broadcast in the thread pool.

Future compatibility note

Future versions of Rayon might vary the number of threads over time, but this method will always return the number of threads which are actually receiving your particular broadcast call.
