[jira] [Updated] (ARROW-17258) [C++] Handling of array-only types using VisitTypeInline
[ https://issues.apache.org/jira/browse/ARROW-17258?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tobias Zagorni updated ARROW-17258:
-----------------------------------
Docs Text:
This patch prepares Arrow for the new RunLengthEncoded type. Since a run-length encoded scalar does not make any sense, the idea that this type cannot exist as a Scalar.
Scalar visitors currently use TypeTraits::ScalarType, which does not really make sense for RLE.
Implements a separate variant of VisitTypeInline, that should only visit types that can exist as scalar. Uses it in scalar code.
