Struct DcpsTickDriver 

pub struct DcpsTickDriver { /* private fields */ }

Drives a runtime’s periodic tick from an external executor (tokio, an embedded scheduler, a manual test loop). Obtained via DcpsRuntime::tick_driver; only does useful work when the runtime was started with RuntimeConfig::external_tick = true.

Typical loop (the async crate’s spawn_in_tokio shape):

let mut driver = runtime.tick_driver();
let period = driver.tick_period();
while !driver.is_stopped() {
    driver.tick();
    tokio::time::sleep(period).await;
}

Implementations

impl DcpsTickDriver

pub fn tick_period(&self) -> Duration

Period the caller should wait between consecutive Self::tick calls (mirrors the internal zdds-tick thread’s tick_period).

pub fn is_stopped(&self) -> bool

true once the runtime is shutting down (set by Drop/stop()). The driving task must then stop calling Self::tick and return so the runtime can be dropped cleanly.

pub fn tick(&mut self)

Run one tick iteration: periodic SPDP announce, SEDP/WLP ticks, per-user-writer ticks, deadline/lifespan/liveliness checks. Equivalent to one pass of the internal zdds-tick loop body.
