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.

val make_noarg : ?attributes:Attribute.packed list -> ?deps:t list -> ?unused_code_warnings:bool -> (loc:Location.t -> path:string -> 'input_ast -> 'output_ast) -> ('output_ast, 'input_ast) t

Same as make, but without arguments.

val apply : ('output_ast, 'input_ast) t -> name:string -> ctxt:Expansion_context.Deriver.t -> 'input_ast -> (string * Astlib.Ast_500.Parsetree.expression) list -> 'output_ast
