val make : 
  ?attributes:Attribute.packed list ->

make args gen creates a generator that can be passed to Deriving.add to generate an output AST from an input AST and generator arguments.

deps is a list of derivers that this generator depends on.

attributes is deprecated and unused. It is only kept for backward compatibility.

unused_code_warning controls whether unused code warnings (e.g. warnings 32 and 60) are enabled or suppressed in emitted code. Default is false, which suppresses the warnings.

  ?unused_code_warnings:bool ->
  (loc:Location.t -> path:string -> 'input_ast -> 'output_ast) ->
  ('output_ast, 'input_ast) t

Same as make, but without arguments.
