module Constr: sig .. end
The Constr.t represents a single constructor in the extensible variant type. On
creation, one must provide a name for the constructor and a sexp-converter for
serializing the argument to the variant. Both the name and the sexp-converter are
used for display purposes only.
type 'a t
val create : string -> ('a -> Sexplib.Sexp.t) -> 'a t
create name to_sexp
if the type 'a doesn't support sexp conversion, then a good practice
is to use sexp_of_opaque as the converter.
