# Which issue does this PR close? [Variant: Rust API to Create Variant Values #7424](https://github.com/apache/arrow-rs/issues/7424) # Rationale for this change This PR implements a builder-style API for creating Variant values in Rust, following the Variant binary encoding specification. It supports reusing metadata within a single builder session, as discussed in the issue. # What changes are included in this PR? - Add Variants as a canonical Arrow Extension Type (built on top of Struct type). - Introduce `VariantBuilder`, `ObjectBuilder`, and `ArrayBuilder` for constructing Variant values. # Are there any user-facing changes? This PR adds a new public API for programmatically creating Variant-encoded values. No breaking changes. **CC**: @alamb for visibility -- This is an automated message from the Apache Git Service.
