type Uri 

type Uri struct {
	// True if and only if the URI is a SIPS URI.
	Encrypted bool
	Wildcard  bool

	// The user part of the URI: the 'joe' in sip:joe@bloggs.com
	// This is a pointer, so that URIs without a user part can have 'nil'.
	User string

	// The password field of the URI. This is represented in the URI as joe:hunter2@bloggs.com.
	// Note that if a URI has a password field, it *must* have a user field as well.
	// This is a pointer, so that URIs without a password field can have 'nil'.
	// Note that RFC 3261 strongly recommends against the use of password fields in SIP URIs,
	// as they are fundamentally insecure.
	Password string

	// The host part of the URI. This can be a domain, or a string representation of an IP address.
	Host string

	// The port part of the URI. This is optional, and can be empty.
	Port int

	// Any parameters associated with the URI.
	// These are used to provide information about requests that may be constructed from the URI.
	// (For more details, see RFC 3261 section 19.1.1).
	// These appear as a semicolon-separated list of key=value pairs following the host[:port] part.
	UriParams HeaderParams

	// Any headers to be included on requests constructed from this URI.
	// These appear as a '&'-separated list at the end of the URI, introduced by '?'.
	// Although the values of the map are sip.strings, they will never be NoString in practice as the parser
	// guarantees to not return blank values for header elements in SIP URIs.
	// You should not set the values of headers to NoString.
	Headers HeaderParams
