   cc @maartenbreddels, have a look at arrow/compute/kernels/scalar_string_ascii.cc for the example function implementations (valid both for 32-bit and 64-bit offset string types). As more functions are added, common structures will emerge to enable implementing and testing them to be easier and easier.
