type Key = ByteStringSource
type Value = ByteStringSource
stat :: Maybe Key -> RequestSource
Fetch statistics about the cahce. Returns a sequence of responses.
addOpaque :: Opaque -> Request -> RequestSource
Add an opaque marker to a request. This is returned unchanged in the corresponding response.
addCAS :: CAS -> Request -> RequestSource
Add a version tag to a request. When added to a set/replace request, the request will fail if the data has been modified since the CAS was retrieved for the item.
