Implementations§

Source§

impl SemaphoreMetrics

Source

fn new(cfg: PersistConfig, registry: MetricsRegistry) -> Self

Source

async fn fetch(&self) -> &MetricsSemaphore

We can’t easily change the number of permits, and the dyncfgs are all set to defaults on process start, so make sure we only initialize the semaphore once we’ve synced dyncfgs at least once.

Source

pub(crate) async fn acquire_fetch_permits( &self, encoded_size_bytes: usize, ) -> MetricsPermits
