**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** The embedded field type of a List must always be called "item" -- you can see this is done everywhere in the arrow-rs codebase that a `DataType::List` is created: https://github.com/search?q=repo%3Aapache%2Farrow-rs+%22%5C%22item%5C%22%22&type=code While working on https://github.com/influxdata/influxdb_iox/pull/8247 I had to make this change ```diff - DataType::List(Arc::new(Field::new("state", dt.clone(), false))), + DataType::List(Arc::new(Field::new("item", dt.clone(), true))), ``` to align the type with expected Having to do this is both verbose/annoying but more to the point means we are exposing some sort of implementation detail that must be [cargo-culted](https://en.wikipedia.org/wiki/Cargo_cult_programming) in many places **Describe the solution you'd like** I would like a method like this (with good documentation) to create a ```rust let dt = DataType::new_list(DataType::Float64, true); ``` That would do the same thing as ```rust let df = DataType::List(Arc::new(Field::new("item", DataType::Float64, true))), ``` cc @tustvold for your thoughts **Describe alternatives you've considered** Do nothing **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
