}

A known path attribute or raw preserved bytes.

Known attributes are decoded into typed variants. Unknown attributes are preserved as RawAttribute for pass-through with the Partial bit.

Variants

Origin(Origin)

ORIGIN attribute (type 1).

AsPath(AsPath)

AS_PATH attribute (type 2).

NextHop(Ipv4Addr)

NEXT_HOP attribute (type 3).

LocalPref(u32)

LOCAL_PREF attribute (type 5).

Med(u32)

MULTI_EXIT_DISC attribute (type 4).

Communities(Vec<u32>)

RFC 1997 COMMUNITIES — each u32 is high16=ASN, low16=value.

ExtendedCommunities(Vec<ExtendedCommunity>)

RFC 4360 EXTENDED COMMUNITIES.

LargeCommunities(Vec<LargeCommunity>)

RFC 8092 LARGE COMMUNITIES.

OriginatorId(Ipv4Addr)

RFC 4456 ORIGINATOR_ID — original router-id of the route.

ClusterList(Vec<Ipv4Addr>)

RFC 4456 CLUSTER_LIST — list of cluster-ids traversed.

MpReachNlri(MpReachNlri)

RFC 4760 MP_REACH_NLRI.

MpUnreachNlri(MpUnreachNlri)

RFC 4760 MP_UNREACH_NLRI.

PmsiTunnel(PmsiTunnel)

RFC 6514 §5 PMSI Tunnel — used by EVPN Type 3 IMET for ingress-replication BUM forwarding.

OnlyToCustomer(u32)

RFC 9234 §5 Only-to-Customer (type 35) — carries the 32-bit ASN that initially set OTC on the route. Optional + Transitive (0xC0).

Unknown(RawAttribute)

Unknown or unrecognized attribute, preserved for re-advertisement.

Implementations

impl PathAttribute

pub fn type_code(&self) -> u8

Return the type code of this attribute.

pub fn flags(&self) -> u8

Return the wire flags for this attribute.

Trait Implementations

impl Clone for PathAttribute

fn clone(&self) -> PathAttribute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathAttribute

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

Formats the value using the given formatter.

impl Hash for PathAttribute

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 PathAttribute

fn eq(&self, other: &PathAttribute) -> 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.
