maybe_parallel_iterator
Write your code once. Then toggle between sequential and parallel iterators with a feature flag!
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
- Iterators
into_maybe_par_iter
maybe_par_iter
maybe_par_iter_mut
- Sorts

Use the rayon
feature flag to enable rayon parallelism.
The default is sequential ("rayoff" mode).
Limitations

collect
- *
enumerate
filter_map
find_any
flat_map
for_each
