[GitHub] [arrow] jorgecarleitao opened a new pull request #9019: ARROW-11040: [Rust] Simplified builders

jorgecarleitao opened a new pull request #9019:
URL: https://github.com/apache/arrow/pull/9019


   This is a draft PR that simplifies the builders code. It has no semantic, execution or API change. It currently depends on pending PRs and therefore is a draft.
   
   The main idea here is to generalize `[Large]ListBuilder`, `[Large]StringBuilder`, `[Large]BinaryBuilder` as `GenericListBuilder`, `GenericStringBuilder` and `GenericBinaryBuilder` respectively, thereby removing duplicated code.
   
   The relevant changes in this PR are on `src/array/builders.rs` only.
