> A StructType is basically a Schema (vector of Fields), right? Likewise, a
> StructArray is pretty much the same as a RecordBatch, right? Schema and
> RecordBatch have many more methods than StructType/StructArray, but we should
> be able to do the same kinds of things to structs.
> Also, an observation while working on ARROW-11423: the method to extract an
> Array column from a StructArray is called {{field()} and
> {{GetFieldByName()}}, which is confusing since Schema/StructType is what
> contains Field objects, and {{StructArray::field()}} returns Array, not Field.
