name to address
data SocketAddr Source #
IPv4 or IPv6 socket address, i.e. the sockaddr_in
or sockaddr_in6
struct.
Example on JSON instance:
> JSON.encodeText $ ipv6 "3731:54:65fe:2::a8" 9090 "{"addr":[14129,84,26110,2,0,0,0,168],"port":9090,"flow":0,"scope":0}" > JSON.encodeText $ ipv4 "128.14.32.1" 9090 "{"addr":[128,14,32,1],"port":9090}"
Instances
ipv4 :: HasCallStack => CBytes -> PortNumber -> SocketAddr Source #
Convert a string containing an IPv4 addresses to a binary structure
This is partial function, wrong address will throw InvalidArgument
exception.
ipv6 :: HasCallStack => CBytes -> PortNumber -> SocketAddr Source #
Convert a string containing an IPv6 addresses to a binary structure
This is partial function, wrong address will throw InvalidArgument
exception.
withSocketAddr :: SocketAddr -> (Ptr SocketAddr -> IO a) -> IO a Source #
Pass SocketAddr
to FFI as pointer.
withSocketAddrUnsafe :: SocketAddr -> (MBA# SocketAddr -> IO a) -> IO a Source #
Pass SocketAddr
to FFI as pointer.
USE THIS FUNCTION WITH UNSAFE FFI CALL ONLY.
sizeOfSocketAddr :: SocketAddr -> CSize Source #
withSocketAddrStorage :: (Ptr SocketAddr -> IO ()) -> IO SocketAddr Source #
Allocate space for sockaddr_storage
and pass to FFI.
withSocketAddrStorageUnsafe :: (MBA# SocketAddr -> IO ()) -> IO SocketAddr Source #
Allocate space for sockaddr_storage
and pass to FFI.
USE THIS FUNCTION WITH UNSAFE FFI CALL ONLY.
IPv4 address
Independent of endianness. For example 127.0.0.1
is stored as (127, 0, 0, 1)
.
For direct manipulation prefer ipv4AddrToTuple
and tupleToIPv4Addr
.
JSON instance encode ipv4 address into an array with 4 Word8
octets.

224.0.0.0
ipv4AllHostsGroup :: IPv4 Source #
224.0.0.1
ipv4MaxLocalGroup :: IPv4 Source #
224.0.0.255
ipv4AddrToTuple :: IPv4 -> (Word8, Word8, Word8, Word8) Source #
Converts IPv4
to representation-independent IPv4 quadruple.
For example for 127.0.0.1
the function will return (127, 0, 0, 1)
regardless of host endianness.
IPv6 address
Independent of endianness. For example ::1
is stored as (0, 0, 0, 1)
.
For direct manipulation prefer ipv6AddrToTuple
and tupleToIPv6Addr
.
JSON instance encode ipv6 address into an array with 8 Word16
octets.
Instances
ipv6Loopback :: IPv6 Source #
::1
ipv6AddrToTuple :: IPv6 -> (Word16, Word16, Word16, Word16, Word16, Word16, Word16, Word16) Source #
convert IPv6
to octets.
tupleToIPv6Addr :: (Word16, Word16, Word16, Word16, Word16, Word16, Word16, Word16) -> IPv6 Source #
convert IPv6
from octets.
port numbber
newtype PortNumber Source #
Port number.
Use the Num
instance (i.e. use a literal) to create a -- PortNumber
value.
