I see. Is the proposed solution something like:

ArrayBase::iter(myarray).unwrap()

or should I explicitly recast at ArrayBase before calling .iter()?

cschwan commented 2 years ago

That's the question, I don't understand the warning.

alecandido commented 2 years ago

Me too...

felixhekhorn commented 2 years ago

iter pointing to NpySingleIter (also deprecated) to lanes (I guess)

alecandido commented 2 years ago

Lanes are a more complicated concept, I'm not sure we want that one, but we might have a look.
