maybeparalleliterator

Write your code once. Then toggle between sequential and parallel iterators with a feature flag!

rust let a: Vec<i32> = (0..100).collect(); a.into_maybe_parallel_iterator() .with_min_sequential(2) .map(|n| -n) .enumerate() .flat_map(|(e, n)| vec![e as i32, n, n + 1000].into_maybe_parallel_iterator()) .for_each(|item| { println!("par: {:?}", item); })

Features

• into_maybe_par_iter
• maybe_par_iter
• maybe_par_iter_mut

Use the rayon feature flag to enable rayon parallelism.

The default is sequential ("rayoff" mode).

Limitations

For now, only supports:

• *enumerate
• find_any
• flat_map
• for_each
• map
• *with_min_sequential (no-op unless rayon feature enabled)

*Only available for IndexedParallelIterator's if rayon feature enabled.
