Type-safe marshalling between processes of the same executable
This is a pragmatic approach to type-safe marshalling. We define
type encap
as an arbitrary value that carries a type identifier with it.
The type identifier is generated when the functor
Netplex_encap.Make_encap is applied. Every instantiation of this
functor generates a new type identifier.
The idea is then that an encap
value can be marshalled to another
process using Marshal
, and when it is unwrapped the type identifier
is checked. Unwrapping is only successful when the unwrap
function
from the same functor instantiation is used as the wrap
function.
This module is incompatible with:
let module
expressions.Only some of these assumptions can be checked at runtime by this implementation.
Raised when an encapulated type is tried to be unwrapped by the wrong encapsulation module
