Expand description

IETF RFC 7346 第 2 节 中定义的 IPv6 多播地址 的范围。

稳定性保证

并非多播作用域的所有可能值都已分配。 未来的 RFC 可能会引入新的作用域,它将作为变体添加到此枚举中; 因此,枚举被标记为 #[non_exhaustive]

Examples

#![feature(ip)]

use std::net::Ipv6Addr;
use std::net::Ipv6MulticastScope::*;

// 具有全局作用域 (`ff0e::`) 的 IPv6 多播地址。
let address = Ipv6Addr::new(0xff0e, 0, 0, 0, 0, 0, 0, 0);

// 将打印 "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)§

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

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

Interface-Local 作用域。

§

LinkLocal

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

Link-Local 作用域。

§

RealmLocal

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

Realm-Local 作用域。

§

AdminLocal

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

Admin-Local 作用域。

§

SiteLocal

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

Site-Local 作用域。

§

OrganizationLocal

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

Organization-Local 作用域。

§

Global

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

Global 作用域。
