Struct NetworkClock 

pub struct NetworkClock { /* private fields */ }

NTP-style network clock: estimates server time from ping round-trips.

Call record_ping_pong each time a pong arrives, then query server_time(local_time) to get the best estimate of current server time.

Implementations

impl NetworkClock

pub fn new() -> Self

pub fn record_ping_pong( &mut self, send_time_s: f64, recv_time_s: f64, server_send_time_s: f64, )

Call when a pong arrives.

• send_time_s — local time (seconds) when we sent the ping.
• recv_time_s — local time (seconds) when we received the pong.
• server_send_time_s — the server’s timestamp embedded in the pong.

pub fn tick(&mut self, dt: f64)

Advance the clock correction by dt seconds. Should be called each game frame.

pub fn server_time(&self, local_time_s: f64) -> f64

Best estimate of the current server time given local_time_s.

pub fn to_server_tick(&self, local_time_s: f64, tick_rate_hz: f64) -> u64

Convert a local time to server tick given tick rate.

pub fn rtt_ms(&self) -> f64

pub fn offset_s(&self) -> f64

pub fn sample_count(&self) -> u64

Trait Implementations

impl Default for NetworkClock

fn default() -> Self

Returns the “default value” for a type.
