Module Std.Type_generic

module Type_generic: Type_generic

type 'a computation

Examples of computation:

type sexp_of_t = ('a -> Sexp.t) computation type type_struct = Type_struct.t computation

The term generic is used to refer to a specific implementation of a computation whose concrete implementation is programmed using the type representation of values.

For example, when one uses with sexp as a way to implement the sexp_of_t computation, the technique used is code generation at compile time. Another approach is to define a generic function sexp_of_t that inspects the representation of the type at runtime.

This module offers an abstraction over type rep in order to implement generics in a efficient way.

Provided from a user enough pieces of implementation regarding a particular computation, this module returns essentially the following function:

(** main function : get the computation from the typerep *) val of_typerep : 'a Typerep.t -> `generic of 'a computation

that allows one to get the generic computation operating on a given type 'a.
