Struct MplsLabel 

pub struct MplsLabel(pub u32);

A 3-byte MPLS label field (RFC 3032) as carried in EVPN NLRI.

For VXLAN-encapsulated EVPN (RFC 8365), the 24-bit label field carries a 24-bit VNI. The codec does not distinguish — consumers interpret the value based on the Encapsulation extended community.

Implementations

impl MplsLabel

pub const fn new(value: u32) -> Self

Construct from a raw 24-bit value (upper 8 bits ignored).

pub const fn value(&self) -> u32

Raw 24-bit value.

pub const fn as_vni(&self) -> u32

Interpret this field as a VXLAN VNI (RFC 8365 §5).

The label field on the wire is (label << 4) | (TC << 1) | S when used for MPLS, but for VXLAN the full 24 bits are the VNI. Both uses call this accessor; it’s up to the caller to know the encap.

pub const fn as_mpls_label(&self) -> u32

Extract the 20-bit MPLS label field (upper 20 bits of the 24-bit word).

Trait Implementations

impl Clone for MplsLabel

fn clone(&self) -> MplsLabel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MplsLabel

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

Formats the value using the given formatter.

impl Hash for MplsLabel

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 Ord for MplsLabel

fn cmp(&self, other: &MplsLabel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MplsLabel

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

impl PartialOrd for MplsLabel

fn partial_cmp(&self, other: &MplsLabel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
