Asynchronous messaging interface to the Hydra Network, e.g to other Hydra nodes.
Concrete implementations are provided by submodules. Import those instead of this one if interested in actually configuring and running a real network layer.
Incoming and outgoing messages are modelled as Message
data type.
Synopsis
- newtype Network m msg = Network {
- broadcast :: msg -> m ()
- newtype NetworkCallback msg m = NetworkCallback {
- deliver :: msg -> m ()
- type NetworkComponent m inbound outbound a = NetworkCallback inbound m -> (Network m outbound -> m a) -> m a
- data IP
- data Host = Host {
- hostname :: Text
- port :: PortNumber
- newtype NodeId = NodeId {}
- showHost :: Host -> String
- readHost :: MonadFail m => String -> m Host
- data PortNumber
- readPort :: MonadFail m => String -> m PortNumber
- close :: Socket -> IO ()
Types
newtype Network m msg Source #
Interface from the application to the network layer.
newtype NetworkCallback msg m Source #
Interface from network layer to the application. XXX: Reliably delivering a message in the crash-recovery fault model is tricky. According to "Introduction to Reliable and Secure Distributed Programming" section "2.2.4 Crashes with recoveries" explains that storing to stable storage and just pointing to stored events is a better way.
NetworkCallback | |
|
type NetworkComponent m inbound outbound a = NetworkCallback inbound m -> (Network m outbound -> m a) -> m a Source #
A type tying both inbound and outbound messages sending in a single Component.
A NetworkComponent
can have different inbound and outbound message types.
