Synopsis

Inet

data Inet Source #

InetAddress

data InetAddress Source #

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

Use inetAddressFromTuple and inetAddressToTuple for constructing and deconstructing custom addresses.

Hint: Use the Storable instance. 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}]

InetPort

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

Instances

Eq (SocketAddress Inet6) # 
Eq (SocketAddress Inet) # 
Show (SocketAddress Inet6) # 
Show (SocketAddress Inet) # 
Storable (SocketAddress Inet6) # 
Storable (SocketAddress Inet) # 
data SocketAddress Inet6 Source #

An IPv6 socket address.

The socket address contains a port number that may be used by transport protocols like TCP.

SocketAddressInet6 inet6Loopback 8080 0 0
data SocketAddress Inet Source #

An IPv4 socket address.

The socket address contains a port number that may be used by transport protocols like TCP.

SocketAddressInet inetLoopback 8080

Custom addresses

inetAddressFromTuple

inetAddressFromTuple :: (Word8, Word8, Word8, Word8) -> InetAddress Source #

Constructs a custom InetAddress.

inetAddressFromTuple (127,0,0,1) == inetLoopback

inetAddressToTuple

Special addresses

inetAllHostsGroup

inetNone

inetNone :: InetAddress Source #
