Data types support module.

Data is a collection of bits, that can be stored and loaded on some media. This module provides functions for doing this in a generic way.

To be on a safe side, we insist on explicit versioning of each data representation. Otherwise, any OCaml value is suitable for this module.

The module defines interfaces Data.S that describes the expected set of functions for data. It also defines a Cache.S interface, that is useful for caching data that is hard to obtain.

type ('a, 'b) copy = 'b -> 'a -> int -> unit

copy buf obj pos is a method to copy object obj into a buffer buf, starting from a position pos and will return the number of bytes written. XXX: we need the amount of bytes beforehand.

type ('a, 'b) dump = 'b -> 'a -> unit

dump out obj a type of functions that outputs a value obj into output out

type lexbuf = Lexing.lexbuf
type scanbuf = Scanf.Scanning.scanbuf
module Versioned : sig ... end

Versioned interfaces

val marshal_reader : (module Core_kernel.T with type t = 'a) -> 'a reader

marshal_reader (module T) returns a reader in OCaml Marshal format.

val marshal_writer : (module Core_kernel.T with type t = 'a) -> 'a writer

marshal_writer (module T) returns a writer in OCaml Marshal format.

val sexp_reader : (module Core_kernel.Sexpable with type t = 'a) -> 'a reader

sexp_reader (module T) returns a reader in sexp format.

sexp_writer (module T) returns a writer in sexp format.

val sexp_writer : (module Core_kernel.Sexpable with type t = 'a) -> 'a writer

sexp_writer (module T) returns a writer in sexp format.

val bin_reader : (module Core_kernel.Binable with type t = 'a) -> 'a reader

bin_reader (module T) returns a reader in binprot format.

val bin_writer : (module Core_kernel.Binable with type t = 'a) -> 'a writer

bin_writer (module T) returns a writer in binprot format.

val pretty_writer : (module Core_kernel.Pretty_printer.S with type t = 'a) -> 'a writer

pretty_printer (module T creates a writer that uses T.pp function for outputting.

module type S = sig ... end

Data type interface.

module Make (T : Versioned.S) : S with type t := T.t

Implements Data.S interface from the provided minimal implementation.

module Read : sig ... end

Read typeclass.

module Write : sig ... end

Write typeclass.

module Cache : sig ... end

Generic caching.
