URL: https://github.com/apache/arrow-rs/issues/3702
Hi,I'm new to Rust and I really like the Rust language and the project. This
is what came to mind when I read the code for this project.
**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
The existed method `GenericListArray::from_iter_primitive` can only create
Array of `List<T>`,it can't create Array of `List<List<T>>`and other more
nested List.
**Describe the solution you'd like**
Is possible to implement GenericListArray::from_iter so we can create
GenericListArray like this:
```Rust
// create ListArray [[[1,2],null],[[3]]]
let data = vec![
Some(vec![Some(vec![Some(1), Some(2)]), None]),
Some(vec![Some(vec![Some(3)])]),
];
let list_array =
GenericListArray::<i32>::from_iter::<Int32Type,..?>(data);
```
**Describe alternatives you've considered**
Is there a way to support arbitrary nesting depth of list handlers via
generic implementation？
I'm curious if Rust's metaprogramming is powerful enough to implement this
feature.
