A validation checker for multiaddrs. Some basic validators for common address types are provided, but creating your own combinations is easy.
a, _ := ma.NewMultiaddr("/ip4/18.104.22.168/tcp/1708") TCP.Matches(a) // returns true
Making your own validators is easy, for example, the
Reliable multiaddr is
defined as follows:
// Define IP as either ipv4 or ipv6 var IP = Or(Base(ma.P_IP4), Base(ma.P_IP6)) // Define TCP as 'tcp' on top of either ipv4 or ipv6 var TCP = And(IP, Base(ma.P_TCP)) // Define UDP as 'udp' on top of either ipv4 or ipv6 var UDP = And(IP, Base(ma.P_UDP)) // Define UTP as 'utp' on top of udp (on top of ipv4 or ipv6) var UTP = And(UDP, Base(ma.P_UTP)) // Now define a Reliable transport as either tcp or utp var Reliable = Or(TCP, UTP) // From here, we can easily define multiaddrs for protocols that can run on top // of any 'reliable' transport (such as ipfs)
NOTE: the above patterns are already implemented in package
