Dandandan opened a new pull request #9619: URL: https://github.com/apache/arrow/pull/9619
This changes the code to use `slice::clone_from` (https://doc.rust-lang.org/std/clone/trait.Clone.html#method.clone_from) instead of `x = y.clone()` which saves some allocations. This gives a small speed up when reading parquet files. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
