/*
Multiaddr is a cross-protocol, cross-platform format for representing
internet addresses. It emphasizes explicitness and self-description.
Learn more here: https://github.com/multiformats/multiaddr
Multiaddrs have both a binary and string representation.

// Equal returns whether two Multiaddrs are exactly equal

// Bytes returns the []byte representation of this Multiaddr

// This function may expose immutable, internal state. Do not modify.
Bytes() []byte
// String returns the string representation of this Multiaddr
// (may panic if internal state is corrupted)
String() string
// Protocols returns the list of Protocols this Multiaddr includes
// will panic if protocol code incorrect (and bytes accessed incorrectly)

// /ip4/1.2.3.4 encapsulate /tcp/80 = /ip4/1.2.3.4/tcp/80

// Decapsultate removes a Multiaddr wrapping. For example:
//
// /ip4/1.2.3.4/tcp/80 decapsulate /ip4/1.2.3.4 = /tcp/80
//
Decapsulate(Multiaddr) Multiaddr
// ValueForProtocol returns the value (if any) following the specified protocol
//
// Note: protocols can appear multiple times in a single multiaddr.
// Consider using `ForEach` to walk over the addr manually.
