Synopsis

Documentation

get :: MonadRedis m => RedisStructure (BASIC w) a b -> a -> m b Source #

Simple get command. Works on RedisBasic a b and RedisIntegral a b.

liftq :: RedisStructure (BASIC w) a b -> a ⟿ b Source #

Construct a query to be used with mget. You may combine many of these together to create complex queries. Use mget to execute the query back in the Redis monad. Works on RedisBasic a b and RedisIntegral a b.

mget :: MonadRedis m => (a ⟿ b) -> a -> m b Source #

Reify a (⟿) query into the Redis monad via a single mget command.

set :: MonadRedis m => RedisStructure (BASIC w) a b -> a -> b -> m () Source #

Set a value for a given key. Works on RedisBasic a b and RedisIntegral a b.

set' :: MonadRedis m => RedisBasic a (Maybe b) -> a -> b -> m () Source #

Convenient alias for setting a value for an optional path

incr :: MonadRedis m => RedisIntegral a b -> a -> m b Source #

Increment an Integer in Redis. Empty values are treated as 0.

incrby :: MonadRedis m => RedisIntegral a b -> a -> b -> m b Source #

Increment an Integer in Redis by a specific amount. Empty values are treated as 0.

decr :: MonadRedis m => RedisIntegral a b -> a -> m b Source #

Decrement an Integer in Redis. Empty values are treated as 0.

decrby :: MonadRedis m => RedisIntegral a b -> a -> b -> m b Source #

Decrement an Integer in Redis by a specific amount. Empty values are treated as 0.
