README
Vault is a tiny library that provides a single data structure called vault.
A vault is a type-safe, persistent storage for values of arbitrary types. Like IORef
, I want to be able to store values of any type in it, but unlike IORef
, I want the storage space to behave like a persistent, first-class data structure, as appropriate for a purely functional language.
It is analogous to a bank vault, where you can access different bank boxes with different keys; hence the name.
In other words, a vault is an abstract data type with the following basic signature
data Key a
data Vault
newKey :: IO (Key a)
empty :: Vault
lookup :: Key a -> Vault -> Maybe a
insert :: Key a -> a -> Vault -> Vault
delete :: Key a -> Vault -> Vault
A few common functions for finite maps, like adjust
and union
, are provided as well.
This library was created thanks to the feedback on my blog post Vault - a persistent store for values of arbitrary types.
Installation
The whole thing is available on hackage, so you just have to type
cabal update
cabal install vault
