[jira] [Updated] (ARROW-10892) [Rust] Introduce safe and performant
iterators over elements of arrays
[ https://issues.apache.org/jira/browse/ARROW-10892?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Lamb updated ARROW-10892:
--------------------------------
Summary: [Rust] Introduce safe and performant iterators over elements of arrays (was: [Rust] Introduce iterators over elements of arrays)
> [Rust] Introduce safe and performant iterators over elements of arrays
> ----------------------------------------------------------------------

> Key: ARROW-10892
> URL: https://issues.apache.org/jira/browse/ARROW-10892
> Project: Apache Arrow
> Issue Type: Bug
> Reporter: Daniël Heres
> Priority: Minor
>
> The value functions in the primitive / string / etc arrays are often used to get elements at i in a loop. Some of them don't have boundary checks for performance reasons, so usage of them is unsafe.
> We should introduce a safe iterator over the elements (T instead of Option<T>) that doesn't do boundary checks and can be used to iterate over the elements of the array. Maybe values_iter would be a good name?
