Description

This module implements the Minecraft protocol's keep-alive mechanism, which helps detect stale connections by periodically exchanging random numbers.

Synopsis

data KeepAliveFail a
- = KeepAliveFail a a
- | KeepAliveTimeout
skeepalive :: forall a (es :: [Effect]) void. (Concurrent :> es, Talking' es, IOE :> es, Random a, Show a, Eq a, Pack a, Unpack a, Typeable a) => Eff es void
