Synopsis

Documentation

hgetall :: MonadRedis m => RedisHSet a s b -> a -> m [(s, b)] Source #

Retrieve all elements of an HSet

hget :: MonadRedis m => RedisHSet a s b -> a -> s -> m (Maybe b) Source #

Lookup via key and subkey

hmget :: (MonadRedis m, Traversable t) => RedisHSet a s b -> a -> t s -> m (t (s, Maybe b)) Source #

Lookup via key and subkeys, pairing each given subkey with the lookup result

hset :: MonadRedis m => RedisHSet a s b -> a -> s -> b -> m (ActionPerformed Creation) Source #

Set via key and subkey

hmset :: (MonadRedis m, Traversable t) => RedisHSet a s b -> a -> t (s, b) -> m () Source #

Set via key and subkeys

hdel :: (MonadRedis m, Traversable t) => RedisHSet a s b -> a -> t s -> m (ActionPerformed Deletion) Source #

Delete via key and subkeys

hsetnx :: MonadRedis m => RedisHSet a s b -> a -> s -> b -> m (ActionPerformed Creation) Source #

Set a value only if it does not currently exist in the HSET

hscan :: RedisHSet a s b -> a -> Cursor -> Redis (Maybe Cursor, [(s, b)]) Source #

Use a cursor to iterate a collection
