[back to package description]hs-multiaddr
A multiaddr implementation in Haskell. Multiaddr is a self-describing network address format supporting a variety of protocols, with both string and binary representations.
Installation
We're on Hackage, so just add multiaddr to your cabal build-depends.
Usage
import Network.Multiaddr
let Just somewhere = readMultiaddr "/ip4/8.8.8.8/tcp/80"
protocolNames somewhere -- ["ip4", "tcp"]
-- Encapsulation
-- Multiaddr is a monoid, `encapsulate` is just an alias for (<>)
let Just proxy = readMultiaddr "/ip6/::1/tcp/443"
let proxied = proxy `encapsulate` somewhere
toText proxied -- "/ip6/::1/tcp/443/ip4/8.8.8.8/tcp/80"
hasIPv6 proxied -- True
-- Grab an individual part of the address
parts proxied !! 2 -- "/ip4/8.8.8.8"
-- Encode into a ByteString
let bytes = encode proxied
-- Decode and get back the original!
let Just decoded = decode bytes
decoded == proxied -- True
