Can we have one StructPlan that returns
structornamed_structbased on the values?let mut create_struct_args = if is_named_struct { self.create_named_struct_expr(values, schema, planner_context)? } else { self.create_struct_expr(values, schema, planner_context)? };The logic here should be inside planner
@jayzhan211 Is this what u suggesting ?
If you were suggesting to move create_struct_expr & create_named_struct_expr to planner. I see an issues over there i.e these functions intnerally call self.sql_expr_to_logical_expr. I would rather have it here to keep it simple. Sorry if i understood it wrong.

Based on my understanding we also have a named_struct function which is an alias for struct function with input expressions optionally named.
In this PR i am not moving named_struct function to udp.
My understanding was to move create_named_struct & create_struct which were solely handling struct function.

Right, they are not possible to move into the planner. Another thing we can improve on is, forgetting about create_struct_expr and use create_named_struct_expr and named_struct. But, we can change this in next PR

Liked mentioned earlier. Thats a great idea, i will make the change in another PR. Thanks for your help @jayzhan211
