Highlights

• Parallel Zip
• Parallel elementwise (no order) iterator
• Parallel .axis_iter() (and _mut)
• .par_map_inplace() for arrays.

Status and Lookout

• Still iterating on and evolving the crate

  • A separate crate is less convenient (doesn't use rayon IntoParallelIterator trait, but a separate trait) but allows rapid iteration and we can follow the evolution of rayon's internals. This crate is double pace: For every ndarray or rayon major version, this crate goes up one major version.

• Performance:

  • TBD. Tell me about your experience.
  • You'll need a big chunk of data (or an expensive operation per data point) to gain from parallelization.

How to use with cargo::
