Please describe what you are trying to do.** This is a tracking ticket for work items identified by - https://github.com/apache/arrow-rs/pull/8167 **Describe the solution you'd like** Several things: - [ ] https://github.com/apache/arrow-rs/issues/8170 - [ ] `ObjectBuilder` should detect duplicates at insertion time, not at finish - [ ] Refactor `ParentState` to track and rollback state on behalf of its owning builder - [ ] Rework `ValueBuffer` API to work with `ParentState` for reliable nested rollbacks - [ ] Rename `ValueBuffer` as `ValueBuilder` and make it public - [ ] `VariantArrayBuilder` tracks starting offsets instead of (offset, len) pairs - [ ] `VariantArrayBuilder` uses `ParentState` for simpler rollbacks - [ ] Add fallible and infallible pairs for `new_object` and `new_list` to `VariantBuilderExt` trait. - [ ] Make metadata builders reusable, with `finish` taking `&mut self` instead of `self` - [ ] Turn `MetadataBuilder` into a trait, with the current metadata builder as the canonical implementation - [ ] https://github.com/apache/arrow-rs/issues/8152 **Describe alternatives you've considered** - https://github.com/apache/arrow-rs/pull/7915 **Additional context** Part of the variant shredding saga. -- This is an automated message from the Apache Git Service.
