Module Make.Tree

Tree wraps Store.Tree to avoid encoding/decoding trees more than needed

type kinded_key = Store.Tree.kinded_key
val kinded_key_t : kinded_key Irmin.Type.t
type concrete = Store.Tree.concrete
val concrete_t : concrete Irmin.Type.t
type t =
  1. | Key of kinded_key
  2. | Concrete of concrete
val t : t Irmin.Type.t
