wjones127 opened a new pull request, #5081:
URL: https://github.com/apache/arrow-rs/pull/5081
# Which issue does this PR close?
Closes #4728
# Rationale for this change
Adds cast from list to FixedSizeList. I intend to use this in DataFusion,
where I'd like to allow users to write array literals in SQL (which default to
List) and have the planner cast them to FixedSizeList when appropriate.
# What changes are included in this PR?
`cast_with_options()` now supports `List` to `FixedSizeList`.
# Are there any user-facing changes?
This adds a new feature. A suite of tests are added. Let me know if you
think there are important cases missing.
