Module Data.Record

module Record: sig .. end

Record factory.

You shall start by declaring a (ghost) type r and call Record.signature to create a signature of type r, which will be your container to register your record fields.

Then, populate the signature with Record.field or Record.option. Finally, you shall call Record.publish to pack the record signature and obtain a new data module of type Record with type r = r, which gives you a Data with an opaque type t = r record with fields of type (r,a) field.

      (* ---- Exemple of Record Data --- *)
      type r
      let s = Record.signature () in
      let fd_a = Record.field s ~name:"a" ~descr:"..." (module A) in
      let fd_b = Record.field s ~name:"b" ~descr:"..." (module B) in
      let r = Record.publish s ~page ~kind ~name ~descr
      module M = (val r) : Record with type r = r)

      let make a b = M.default |> M.set fd_a a |> M.set fd_b b
    

type 'a record 

Records of type 'a.

type 'a signature 

Opened signature for record of type 'a.

type ('a, 'b) field 

Field of type 'b for a record of type 'a.

module type S = sig .. end

Data with type t = r record.

val signature : unit -> 'a signature

Create a new, opened record type.

val field : 'r signature ->
name:string ->
descr:Markdown.text ->
?default:'a -> 'a Data.data -> ('r, 'a) field

Adds a field to an opened record.

val option : 'r signature ->
name:string ->
descr:Markdown.text -> 'a Data.data -> ('r, 'a option) field

Adds a optional field to an opened record.

val publish : package:Package.package ->
name:string ->
?descr:Markdown.text ->
'a signature -> (module Data.Record.S with type r = 'a)

Publish and close an opened record.
