Neville Dipale commented on ARROW-4605:
---------------------------------------
Hi [~ntrinquier], for filter, you might consider
fn filter(a: &Array, predicate: &BooleanArray)
so the predicate evaluation is evaluated once, and a boolean array passed to
filter each array.
> [Rust] Move filter and limit code from DataFusion into compute module
