Struct Link 

pub struct Link { /* private fields */ }

A link to a remote endpoint over a transport.

Implementations

impl Link

pub fn new( link_id: LinkId, transport_id: TransportId, remote_addr: TransportAddr, direction: LinkDirection, base_rtt: Duration, ) -> Self

Create a new link in Connecting state.

pub fn new_with_timestamp( link_id: LinkId, transport_id: TransportId, remote_addr: TransportAddr, direction: LinkDirection, base_rtt: Duration, created_at: u64, ) -> Self

Create a link with a creation timestamp.

pub fn connectionless( link_id: LinkId, transport_id: TransportId, remote_addr: TransportAddr, direction: LinkDirection, base_rtt: Duration, ) -> Self

Create a connectionless link (immediately connected).

For connectionless transports (UDP, Ethernet), links are immediately in the Connected state.

pub fn link_id(&self) -> LinkId

Get the link ID.

pub fn transport_id(&self) -> TransportId

Get the transport ID.

pub fn remote_addr(&self) -> &TransportAddr

Get the remote address.

pub fn direction(&self) -> LinkDirection

Get the link direction.

pub fn state(&self) -> LinkState

Get the current state.

pub fn base_rtt(&self) -> Duration

Get the base RTT hint.

pub fn stats(&self) -> &LinkStats

Get the link statistics.

pub fn stats_mut(&mut self) -> &mut LinkStats

Get mutable access to link statistics.

pub fn created_at(&self) -> u64

Get the creation timestamp.

pub fn set_created_at(&mut self, timestamp: u64)

Set the creation timestamp.

pub fn set_connected(&mut self)

Mark the link as connected.

pub fn set_disconnected(&mut self)

Mark the link as disconnected.

pub fn set_failed(&mut self)

Mark the link as failed.

pub fn is_operational(&self) -> bool

Check if this link is operational.

pub fn is_terminal(&self) -> bool

Check if this link is in a terminal state.

pub fn effective_rtt(&self) -> Duration

Get effective RTT (measured if available, else base hint).

pub fn age(&self, current_time_ms: u64) -> u64

Age of the link in milliseconds.

Trait Implementations

impl Clone for Link

fn clone(&self) -> Link

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Link

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

Formats the value using the given formatter.
