# Rationale for this change
As you can see from the arrow docs, `OffsetBufferBuilder` is not in the
arrow crate (it is in arrow_buffe)
https://docs.rs/arrow/latest/arrow/index.html?search=OffsetBufferBuilder

This is a papercut as it means a user needs to add `arrow_buffer` to their
project if they want to use this structure (as we do in DataFusion) such as
https://github.com/apache/datafusion/blob/5e46314c49a0a65785101269c438a26077a7bdb7/datafusion/substrait/Cargo.toml#L34
# What changes are included in this PR?
RE-export `OffsetBufferBuilder` in `arrow::array::OffsetBufferBuilder`,
similarly to `BufferBuilder
https://docs.rs/arrow/latest/arrow/array/struct.BufferBuilder.html
# Are there any user-facing changes?
New export
