class MonadRedis m => RedisCtx m f | m -> f

This class captures the following behaviour: In a context m, a command will return it's result wrapped in a "container" of type f.

Please refer to the Command Type Signatures section of this page for more information.

Instances

RedisCtx RedisTx Queued

RedisCtx Redis (Either Reply)

data Redis a

Context for normal command execution, outside of transactions. Use runRedis to run actions of this type.

In this context, each result is wrapped in an Either to account for the possibility of Redis returning an Error reply.
