`module Hlist : sig ... end`
`include module type of Record_builder__.Record_builder_intf`
`module type Partial_applicative_S : sig ... end`

A subset of the operations of an applicative.

`module type Partial_applicative_S2 : sig ... end`
`module type Make_creator_types : sig ... end`

These are the types used for building records by folding over fields.

`module type Record_builder_S : sig ... end`

Modules of this type are used to traverse a record using a specific applicative. They can be made using the functor `Record_builder.Make`.

`module type Record_builder_S2 : sig ... end`
`module Make : functor (F : Partial_applicative_S) -> Record_builder_S with type 'a applicative = 'a F.t`
`module Make_2 : functor (F : Partial_applicative_S2) -> Record_builder_S2 with type ('a, 'e) applicative = ('a, 'e) F.t`
