Function Finish

cpp/src/arrow/buffer_builder.h:165–174

\brief Return result of builder as a Buffer object. The builder is reset and can be reused afterwards. \param[out] out the finalized Buffer object \param shrink_to_fit if the buffer size is smaller than its capacity, reallocate to fit more tightly in memory. Set to false to avoid a reallocation, at the expense of potentially more memory consumption. \return Status
