data SocketConnection

A SocketConnection encapsulates the state of a single outbound connection.

Constructors

SocketConnection

Fields

• connectionDestination :: TMVar Name
• sendSocketMessage :: Message -> IO ()
• receiveSocketMessage :: IO Message
• disconnectSocket :: IO ()

type Connections = TVar (Map Name Connection)

Mutble Map of Names to Connections.

socketConnect :: Mailboxes -> Connect -> Endpoint -> Name -> IO Connection

Establish a connector for exchanging messages from Endpoint with a destination specified by Name.

socketListen :: Family -> SocketType -> Resolver -> Name -> IO Socket

Listens for new connections on a new Socket, and return the Socket.

messenger :: Mailboxes -> Endpoint -> SocketConnection -> IO ()

Exchange Messages with the Endpoint on the other side of a SocketConnection.

connector :: Mailboxes -> Endpoint -> Name -> Connect -> IO ()

Maintain a Connection between an Endpoint and a destination specified by Name. Should the connection, the connection will automatically be re-attempted.

type Resolver = Name -> IO [SockAddr]

A Resolver translates a name into a list of SockAddr for use with a socket-based Transport.

data ResolverException

Exceptions thrown by a Resolver.

Instances

Show ResolverException

Methods

showsPrec :: Int -> ResolverException -> ShowS

show :: ResolverException -> String

showList :: [ResolverException] -> ShowS

Exception ResolverException

Methods

toException :: ResolverException -> SomeException

fromException :: SomeException -> Maybe ResolverException

displayException :: ResolverException -> String

resolve1 :: Resolver -> Name -> IO SockAddr

Helper to resolve a Name to a single SockAddr for use with a socket-based Transport.

socketResolver4 :: SocketType -> Name -> IO [SockAddr]

Variation of socketResolve for standard IP addresses.

socketResolver6 :: SocketType -> Name -> IO [SockAddr]

Variation of socketResolve for standard IPv6 addresses.

wildcard :: SockAddr -> IO SockAddr

Returns the wildcard SockAddr for the specified SockAddr, if possible.
