Enum NeighborState 

pub enum NeighborState {
    Down,
    Init,
    TwoWay,
    ExStart,
    Exchange,
    Loading,
    Full,
}

OSPF neighbor states (RFC 2328 Section 10.1)

Variants

Down

No information received from neighbor

Init

Hello received, but bidirectionality not established

TwoWay

Bidirectional communication established

ExStart

Master/slave negotiation

Exchange

Database description exchange

Loading

Link state requests being sent

Full

Fully adjacent

Implementations

impl NeighborState

pub fn on_hello_received(self) -> Self

Transition on receiving a Hello packet

pub fn on_two_way_received(self) -> Self

Transition when bidirectionality is confirmed (our router_id seen in neighbor’s Hello)

pub fn on_adjacency_ok(self) -> Self

Transition to begin adjacency formation (DR/BDR or point-to-point)

pub fn on_negotiation_done(self) -> Self

Transition when negotiation completes

pub fn on_exchange_done(self) -> Self

Transition when exchange completes

pub fn on_loading_done(self) -> Self

Transition when loading completes

pub fn on_kill(self) -> Self

Transition on inactivity timeout

pub fn is_adjacent(&self) -> bool

Whether this state represents an established adjacency

Trait Implementations

impl Clone for NeighborState

fn clone(&self) -> NeighborState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NeighborState

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

Formats the value using the given formatter.

impl Default for NeighborState

fn default() -> NeighborState

Returns the “default value” for a type.

impl Ord for NeighborState

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

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

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