If the types are known statically one can use the builder APIs https://docs.rs/arrow-array/latest/arrow_array/builder/index.html#nested-usage If the types are not known statically, it gets much more complicated and will require evaluating the filter predicate on the List::values and then using this in combination with the selection kernels to construct a new ListArray.
