Struct ConnectionState

pub struct ConnectionState {
    pub node_id: NodeId,
    pub room_code: String,
    pub client_name: Option<String>,
    pub connected_at: Instant,
    pub last_ping: Instant,
    pub latency_us: u64,
    pub reconnect_count: u32,
    pub clock_offset: i64,
}

Connection state for a single WebSocket client.

Fields

node_id: NodeId

Unique identifier for this connection.

room_code: String

Room code the client joined.

client_name: Option<String>

Client-provided name (optional).

connected_at: Instant

When the connection was established.

last_ping: Instant

When the last ping/pong was received.

latency_us: u64

Measured round-trip latency in microseconds.

reconnect_count: u32

Number of reconnections for this node.

clock_offset: i64

Clock offset in microseconds (positive = client ahead).

Implementations

impl ConnectionState

pub fn new( node_id: NodeId, room_code: String, client_name: Option<String>, ) -> Self

Create a new connection state.

pub fn update_latency(&mut self, rtt_us: u64)

Update latency from ping/pong exchange.

Arguments

• rtt_us - Round-trip time in microseconds

pub fn update_clock_offset( &mut self, client_send: u64, server_receive: u64, server_send: u64, client_receive: u64, )

Update clock offset from ping/pong exchange.

Uses NTP-style calculation to determine the difference between client and server clocks.

pub fn is_stale(&self, timeout: Duration) -> bool

Check if the connection should be considered stale.

pub fn mark_reconnected(&mut self)

Mark as reconnected, incrementing the counter.

pub fn client_to_server_time(&self, client_time: u64) -> u64

Convert a client timestamp to server time using the clock offset.

pub fn server_to_client_time(&self, server_time: u64) -> u64

Convert a server timestamp to client time using the clock offset.

Trait Implementations

impl Clone for ConnectionState

fn clone(&self) -> ConnectionState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionState

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

Formats the value using the given formatter.
