[jira] [Comment Edited] (ARROW-8025) [C++] Implement cast to Binary and FixedSizeBinary

    [ https://issues.apache.org/jira/browse/ARROW-8025?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17138598#comment-17138598 ]

------------------------------------------------------------------

[~wesm] Cast to and from FixedSizedBinary will involve some more work and I have a couple of questions:

String/Binary to FixedSizedBinary:
- shall we append values one by one and truncate if necessary
- or add as zero copy cast and check that the value offsets indicate same width values
- or both?

FixedSizedBinary to String/Binary is more straightforward to zero copy cast and generate the offset values, although I'm not sure that this cast makes much sense.
