Neville Dipale updated ARROW-4886:
----------------------------------
Priority: Major (was: Blocker)
> [Rust] Inconsistent behaviour with casting sliced primitive array to list
> array
> -------------------------------------------------------------------------------
>
> Key: ARROW-4886
> URL: https://issues.apache.org/jira/browse/ARROW-4886
> Project: Apache Arrow
> Issue Type: Bug
> Components: Rust
> Affects Versions: 0.12.0
> Reporter: Neville Dipale
> Priority: Major
>
> [~csun] I was going through the C++ cast implementation to see if I've missed
> anything, and I noticed that ListCastKernel
> ([https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/kernels/cast.cc#L665])
> doesn't support casting non-zero-offset arrays. So I investigated what
> happens in Rust ARROW-4865. I found an inconsistency where inheriting the
> incoming array's offset could lead us to read invalid data.
> I tried fixing it, but found that a buffer that I expected to be invalid was
> being returned as valid, but returning invalid data.
> I've currently disabled casting primitive to array where the offset is not
> zero, and I'd like to wait for ARROW-4853 so I can see how sliced lists
> behave, and fix this inconsistency. That might only happen in 0.14, so I'm
> fine with that.
