Struct MplsLabelEntry 

pub struct MplsLabelEntry {
    pub label: u32,
    pub traffic_class: u8,
    pub bottom_of_stack: bool,
}

One RFC 8277 MPLS label-stack entry.

Fields

label: u32

The 20-bit MPLS label value.

traffic_class: u8

The 3-bit traffic-class field.

bottom_of_stack: bool

Bottom-of-stack bit.

Implementations

impl MplsLabelEntry

pub fn try_new( label: u32, traffic_class: u8, bottom_of_stack: bool, ) -> Result<Self, EncodeError>

Construct a validated MPLS label-stack entry.

Errors

Returns EncodeError::ValueOutOfRange when label exceeds 20 bits or traffic_class exceeds 3 bits.

pub const fn from_raw(raw: u32) -> Self

Decode a raw 24-bit label-stack entry.

pub fn raw_value(&self) -> Result<u32, EncodeError>

Encode this entry as a raw 24-bit wire value.

Errors

Returns EncodeError::ValueOutOfRange if the public fields contain out-of-range values.

Trait Implementations

impl Clone for MplsLabelEntry

fn clone(&self) -> MplsLabelEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MplsLabelEntry

impl Debug for MplsLabelEntry

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

Formats the value using the given formatter.

impl Eq for MplsLabelEntry

impl Hash for MplsLabelEntry

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 MplsLabelEntry

fn cmp(&self, other: &MplsLabelEntry) -> 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 MplsLabelEntry

fn eq(&self, other: &MplsLabelEntry) -> 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 MplsLabelEntry

fn partial_cmp(&self, other: &MplsLabelEntry) -> 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.
