Enum std::net::Ipv6MulticastScope

#[non_exhaustive]
pub enum Ipv6MulticastScope {
    InterfaceLocal,

🔬This is a nightly-only experimental API. (ip #27709)

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!")
}

Variants (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

🔬This is a nightly-only experimental API. (ip #27709)

Interface-Local scope.

LinkLocal

🔬This is a nightly-only experimental API. (ip #27709)

Realm-Local scope.

AdminLocal

🔬This is a nightly-only experimental API. (ip #27709)

Admin-Local scope.

SiteLocal

🔬This is a nightly-only experimental API. (ip #27709)

Site-Local scope.

OrganizationLocal

🔬This is a nightly-only experimental API. (ip #27709)

Global

🔬This is a nightly-only experimental API. (ip #27709)

Global scope.

Trait Implementations

impl Clone for Ipv6MulticastScope

fn clone(&self) -> Ipv6MulticastScope

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Ipv6MulticastScope

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Ipv6MulticastScope

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Ipv6MulticastScope> for Ipv6MulticastScope

fn eq(&self, other: &Ipv6MulticastScope) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
