`&mut [T]` should implement `rayon::slice::ParallelSliceMut` about rayon

[ewoolsey]

But I can't.

What's the error? As long as you satisfy T: Send and have the traits in scope, it should be fine.

My god I must need some rest. T: Send was the problem. When I saw the error my brain for some reason assumed the missing trait bound was from &mut [T] and not from T...

Apologies for posting this issue, but thanks so much for your help!

This is a more complete example of what I actually want to accomplish

            let (parent_layer, child_layer) = storage.split_at_mut(1 << current_depth);
            parent_layer
                .par_iter_mut()
                .enumerate()
                .for_each(|(i, value)| {
                    let left = &child_layer[2 * i];
                    let right = &child_layer[2 * i + 1];
                    *value = H::hash_node(left, right);
                });

No worries!
