Expand description
Scope of an IPv6 multicast address as defined in IETF RFC 7346 section 2.
Stability Guarantees
Not all possible values for a multicast scope have been assigned.
Future RFCs may introduce new scopes, which will be added as variants to this enum;
because of this the enum is marked as #[non_exhaustive]
.
Examples
#![feature(ip)]
use std::net::Ipv6Addr;
use std::net::Ipv6MulticastScope::*;
// An IPv6 multicast address with global scope (`ff0e::`).
let address = Ipv6Addr::new(0xff0e, 0, 0, 0, 0, 0, 0, 0);
// Will print "Global scope".
match address.multicast_scope() {
Some(InterfaceLocal) => println!("Interface-Local scope"),
Some(LinkLocal) => println!("Link-Local scope"),
Some(RealmLocal) => println!("Realm-Local scope"),
Some(AdminLocal) => println!("Admin-Local scope"),
Some(SiteLocal) => println!("Site-Local scope"),
Some(OrganizationLocal) => println!("Organization-Local scope"),
Some(Global) => println!("Global scope"),
Some(_) => println!("Unknown scope"),
None => println!("Not a multicast address!")
}
RunVariants (Non-exhaustive)
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
InterfaceLocal
Interface-Local scope.
LinkLocal
Link-Local scope.
RealmLocal
Realm-Local scope.
AdminLocal
Admin-Local scope.
SiteLocal
Site-Local scope.
OrganizationLocal
Organization-Local scope.
Global
Global scope.
