Struct MplsLabel 

pub struct MplsLabel(/* private fields */);

MPLS Label value (20-bit, 0-1,048,575)

Implementations

impl MplsLabel

pub const MAX_VALUE: u32 = 0x000F_FFFF

Maximum valid label value (20-bit mask)

pub const IPV4_EXPLICIT_NULL: u32 = 0

IPv4 Explicit NULL label (RFC 3032)

pub const IPV6_EXPLICIT_NULL: u32 = 2

IPv6 Explicit NULL label (RFC 3032)

pub const IMPLICIT_NULL: u32 = 3

Implicit NULL label (RFC 3032)

pub fn try_new(value: u32) -> Result<Self, MplsLabelError>

Create a new MplsLabel with validation. Returns Err if value exceeds 20-bit range.

pub fn value(&self) -> u32

Get the label value (0..=0xFFFFF)

pub fn is_reserved(&self) -> bool

Check if label is in reserved range (0-15 per RFC 3032)

pub fn is_implicit_null(&self) -> bool

Check if label is Implicit NULL (value 3)

pub fn is_ipv4_explicit_null(&self) -> bool

Check if label is IPv4 Explicit NULL (value 0)

pub fn is_ipv6_explicit_null(&self) -> bool

Check if label is IPv6 Explicit NULL (value 2)

pub fn encode(&self, is_bottom: bool) -> [u8; 3]

Encode label to 3-byte wire format per RFC 3032.

Wire format: bits 23-4 = label value, bits 3-1 = reserved (0), bit 0 = Bottom-of-Stack

pub fn decode(bytes: [u8; 3]) -> (Self, bool)

Decode label from 3-byte wire format per RFC 3032.

Returns (label, bottom_of_stack_flag). Note: Reserved bits (3-1) are ignored.

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 Copy for MplsLabel

impl Debug for MplsLabel

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

Formats the value using the given formatter.

impl Eq for MplsLabel

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 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.
