How about
```rust
let mut owned_string = Vec::with_capacity(args.len()-1);
for arg_index in 1..args.len() {
let arg = &args[arg_index];
if !arg.is_null(index) {
owned_string.push(arg.value(index));
}
}
owned_string.join(sep)
```
Or may be there a way to use [kernel
concat](https://docs.rs/arrow/11.0.0/arrow/compute/kernels/concat/index.html)?
