[jira] [Commented] (ARROW-10039) [Rust] Do not require memory alignment of buffers

    [ https://issues.apache.org/jira/browse/ARROW-10039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17204997#comment-17204997 ] 

Jorge Leitão commented on ARROW-10039:
--------------------------------------

Bumped this to 3 as it requires more testing and is not a major blocker, since we do not support the C Data interface yet.

> Currently, all buffers in rust are created aligned. We also panic when a buffer is not aligned. However, [the spec|https://arrow.apache.org/docs/format/Columnar.html#buffer-alignment-and-padding] only recommends, but do not require, memory alignment.
> This issue aims at following the spec more closely, by removing the requirement (not panicking) when memory passed to a buffer is not aligned.
