Constructing columns with data type Array in rust

[HarlanHeilman]

Description

The documentation suggests that arrays and lists are data types that can be found in a column, but there is no method shown for doing this in rust. There are private ChunkBuilder's for arrays, but they are mostly unsafe and not exposed.

There needs to be a simple way of doing this that can be developed and presented on the documentation.
