Database.Redis.Simple
Description
This module is meant to make working with redis in Haskell more simple. It
is a small layer above the full-blown redis package.
It only supports a small subset of the redis features.
- newtype Key = Key {
- unKey :: ByteString
- itemGet :: Binary a => Redis -> Key -> IO (Maybe a)
- itemExists :: Redis -> Key -> IO Bool
- itemSet :: Binary a => Redis -> Key -> a -> IO ()
- itemDelete :: Redis -> Key -> IO ()
- setAdd :: Binary a => Redis -> Key -> a -> IO ()
- setRemove :: Binary a => Redis -> Key -> a -> IO ()
- setContains :: Binary a => Redis -> Key -> a -> IO Bool
- setFindAll :: Binary a => Redis -> Key -> IO [a]
Type for keys
Type for a key in the key-value store
