# What changes are included in this PR?
Added an implementation of `FromIterator<&Option<Ptr>> where Ptr:
AsRef<str>` for `GenericStringArray<OffsetSize>`. The new implementation
converts iterated values into `&str` and wraps in an owned `Option`, then uses
the existing `FromIterator<Option<Ptr>>` implementation to `collect` into a
`GenericStringArray`.
# Are there any user-facing changes?
Users can now create string arrays from `&Option<&str>` iterators. No
breaking changes.
