==========================

Generic facilities for working with `Persistent` classes.

```haskell

{-# language DeriveGeneric #-}

module Main where

import Database.Persist.Generic

data StopLight = Red | Yellow | Green

  deriving (Show, Eq, Generic)

instance PersistField StopLight where

  toPersistValue = genericToPersistValue

  fromPersistValue = genericFromPersistValue

```

### Limitations

  - Only `PersistField` is currently supported.
