Description

Synopsis

Inet

data Inet Source

The Internet Protocol version 4.

Instances

Family Inet Source
HasNameInfo Inet Source
HasAddressInfo Inet Source
Eq (SocketAddress Inet) Source
Show (SocketAddress Inet) Source
Storable (SocketAddress Inet) Source
data SocketAddress Inet = SocketAddressInet { inetAddress :: InetAddress inetPort :: InetPort } Source	An IPv4 socket address. The socket address contains a port number that may be used by transport protocols like TCP. SocketAddressInet inetLoopback 8080

InetAddress

data InetAddress Source

To avoid errors with endianess it was decided to keep this type abstract.

Hint: Use the Storable instance if you really need to access. It exposes it exactly as found within an IP packet (big endian if you insist on interpreting it as a number).

Another hint: Use getAddressInfo for parsing and suppress nameserver lookups:

> getAddressInfo (Just "127.0.0.1") Nothing aiNumericHost :: IO [AddressInfo Inet Stream TCP]
[AddressInfo {addressInfoFlags = AddressInfoFlags 4, socketAddress = SocketAddressInet {inetAddress = InetAddress 127.0.0.1, inetPort = InetPort 0}, canonicalName = Nothing}]

Instances

Eq InetAddress Source
Show InetAddress Source
Storable InetAddress Source

InetPort

data InetPort Source

Instances

Eq InetPort Source
Num InetPort Source
Ord InetPort Source
Show InetPort Source
Storable InetPort Source

SocketAddress Inet

data family SocketAddress f Source

The SocketAddress type is a data family. This allows to provide different data constructors depending on the socket family wihtout knowing all of them in advance or the need to patch this core library.

SocketAddressInet  inetLoopback  8080     :: SocketAddress Inet
SocketAddressInet6 inet6Loopback 8080 0 0 :: SocketAddress Inet6

data SocketAddress Inet6 = SocketAddressInet6 { inet6Address :: Inet6Address inet6Port :: Inet6Port inet6FlowInfo :: Inet6FlowInfo inet6ScopeId :: Inet6ScopeId } Source	An IPv6 socket address.
