Enum NetInterface 

pub enum NetInterface {
    Loopback,
    LocalHost,
    LocalSubnet(IpRange),
    Wan,
    Named(String),
}

Klassifikation eines Netz-Interfaces fuer die Policy-Entscheidung.

Die Engine kann darauf basierend unterschiedlich entscheiden:

• Loopback + LocalHost → oft ProtectionLevel::None (Bytes verlassen den Host nicht).
• LocalSubnet → Management-Netze mit Sign statt Encrypt.
• Wan → restriktivste Policy.
• Named → benutzer-konfigurierte Klassifikation (z.B. tun0 als VPN-geschuetzt, can0-gw als Vehicle-Bus-Gateway).

Variants

Loopback

127.0.0.0/8 oder ::1.

LocalHost

Host-lokaler Transport ausserhalb von Loopback (Shared-Memory, Unix-Domain-Socket) — Bytes verlassen den Host-Kernel nicht.

LocalSubnet(IpRange)

Adresse in einer konfigurierten privaten Range (z.B. 10.0.0.0/24, 192.168.0.0/16).

Wan

Alles andere — oeffentliche IP, unbekanntes Interface.

Named(String)

Benutzer-konfigurierte Interface-Klasse per Name.

Trait Implementations

impl Clone for NetInterface

fn clone(&self) -> NetInterface

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NetInterface

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

Formats the value using the given formatter.

impl Hash for NetInterface

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NetInterface

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

Tests for self and other values to be equal, and is used by ==.

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

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