Struct LabeledNetworkPrefix 

pub struct LabeledNetworkPrefix {
    pub prefix: IpNet,
    pub labels: SmallVec<[MplsLabel; 2]>,
    pub path_id: Option<u32>,
}

A network prefix with MPLS labels (RFC 3107/8277)

Fields

prefix: IpNet

The IP prefix (IPv4 or IPv6)

labels: SmallVec<[MplsLabel; 2]>

MPLS label stack, ordered from top to bottom Uses SmallVec to avoid heap allocations for the common 1-2 label case

path_id: Option<u32>

ADD-PATH path identifier (RFC 7911)

Implementations

impl LabeledNetworkPrefix

pub fn try_new( prefix: IpNet, labels: SmallVec<[MplsLabel; 2]>, path_id: Option<u32>, ) -> Result<Self, LabeledNetworkPrefixError>

Create a new labeled prefix with validation. Returns Err if labels is empty or if total length exceeds 255 bits.

pub fn top_label(&self) -> Option<&MplsLabel>

Get the top label (first in the stack)

pub fn bottom_label(&self) -> Option<&MplsLabel>

Get the bottom label (last in the stack)

pub fn has_multiple_labels(&self) -> bool

Check if the prefix has multiple labels

pub fn label_count(&self) -> usize

Get the number of labels

Trait Implementations

impl Clone for LabeledNetworkPrefix

fn clone(&self) -> LabeledNetworkPrefix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LabeledNetworkPrefix

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

Formats the value using the given formatter.

impl PartialEq for LabeledNetworkPrefix

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