Description:
typed, persistent store for values of arbitrary types; documentation
A vault is a typed, persistent store for values of arbitrary types. It's like having first-class access to the storage space behind IORefs. . The data structure is analogous to a bank vault, where you can access different bank boxes with different keys; hence the name. . This package provides the documentation for a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
