The following are convenience functions that build on Record_builder.field to make it easy to define a t Delimited.Read.t for some record type t.

Example usage:

type t =
  { foo : int
  ; bar : bool
  }
[@@deriving fields]

let read : t Delimited.Read.t =
  Delimited.Read.Fields_O.(
    Fields.make_creator
      ~foo:!!Int.of_string
      ~bar:!?(Option.value_map ~default:true ~f:Bool.of_string)
    |> Delimited.Read.Record_builder.build_for_record)

val (!!) : 
  (string -> 'a) ->
  (_, 'a) Core.Field.t ->
  ('a, _, _, _) Record_builder.Make_creator_types.handle_one_field

Reads a single column from a field of a record.

val (!?) : 
  (string option -> 'a) ->
  (_, 'a) Core.Field.t ->
  ('a, _, _, _) Record_builder.Make_creator_types.handle_one_field

Reads a single column from a field of a record, if the header exists.

( !? ) is to at_header_opt as ( !! ) is to at_header.
