Neville Dipale commented on ARROW-10108:
----------------------------------------
There are a lot of clippy issues with the latest nightly too, perhaps we could
move to the latest nightly after the 2.0.0 release? I'd also like for us to
perform destructive refactors soon as possible after the release (rearranging
the arrow::array module by splitting arrays into their own files)
