}cli only.Expand description
Pre-built service infrastructure. Created by run_app() before run_service().
Apps receive this fully wired – they just use the fields. No boilerplate needed.
On bare metal, K8s-specific features (pre-stop delay, pod metadata in logs) are automatically disabled. On K8s, they’re automatically enabled.
Fields§
§metrics: MetricsManagerMetrics manager – already started, serving endpoints. Use for registering app-specific metrics and metric groups.
dfe: Arc<DfeMetrics>Platform DFE metrics (dfe_* counters/gauges). Already registered.
memory_guard: Arc<MemoryGuard>memory only.Cgroup-aware memory guard. Tracks memory usage for backpressure. Auto-detected from env prefix + cgroup limits.
shutdown: CancellationTokenShutdown token. Cancelled on SIGTERM/SIGINT (with K8s pre-stop delay). Clone and pass to your pipeline loops.
context: &'static RuntimeContextRuntime context – K8s/Docker/BareMetal metadata (pod_name, namespace, etc.).
worker_pool: Option<Arc<AdaptiveWorkerPool>>worker-pool only.Adaptive worker pool for parallel batch processing (worker feature).
None if the worker feature is not enabled or config fails.
batch_engine: Option<Arc<BatchEngine>>worker-batch only.Batch processing engine with SIMD parsing and pre-route filtering
(worker-batch feature). None if worker-batch is not enabled
or worker pool creation failed.
scaling: Option<Arc<ScalingPressure>>scaling only.Scaling pressure calculator for KEDA autoscaling (scaling feature).
None if the scaling feature is not enabled.
governor: Option<SelfRegulationGovernor>governor only.Self-regulation governor (governor feature). Built default-ON (opt-out
via self_regulation.enabled = false) from the cascade. None when
disabled by config – in which case nothing was constructed and the data
path is byte-identical to pre-governor behaviour.
Thread pressure into your
receive transports’ inbound gate / with_pressure hooks, and the
budget is already wired into
the batch_engine governed run path.
Implementations§
Source§impl ServiceRuntime
impl ServiceRuntime
Sourcepub fn set_readiness_check<F: Fn() -> bool + Send + Sync + 'static>(
&mut self,
check: F,
)
pub fn set_readiness_check<F: Fn() -> bool + Send + Sync + 'static>( &mut self, check: F, )
Set the readiness check callback.
Each app defines its own readiness criteria. Call this in run_service()
once you know what “ready” means for your app.
Sourcepub fn batch_engine(&self) -> Option<&Arc<BatchEngine>>
Available on crate feature worker-batch only.
pub fn batch_engine(&self) -> Option<&Arc<BatchEngine>>
worker-batch only.Return the batch processing engine, if the worker-batch feature is
enabled and the worker pool was successfully created.
Sourcepub async fn governed_receiver(
&self,
key: &str,
) -> Result<AnyReceiver, TransportError>
Available on crate features governor and transport only.
pub async fn governed_receiver( &self, key: &str, ) -> Result<AnyReceiver, TransportError>
governor and transport only.Build a governed receive transport from config in ONE call
(governor + transport features).
This is the receive-side analogue of the byte-budget wiring the runtime
already does for the batch_engine: it reads the
transport config at key and threads the runtime’s
governor pressure into the receiver’s inbound brake
(Kafka pause-partitions gate, HTTP/gRPC 503/unavailable shed) so an app
does NOT repeat the gate_actuator -> InboundGate -> with_inbound_gate
dance by hand.
Construction order is respected for free: the
governor was built in build BEFORE
the app calls this in run_service(), so the pressure latch already
exists – this just clones it (an Arc bump) into the transport.
When the governor is disabled (self_regulation.enabled = false,
governor is None) this falls back to the plain
AnyReceiver::from_config
so the data path stays byte-identical to pre-governor behaviour.
§Errors
Returns the underlying transport error if the config is missing/invalid or the backend fails to construct.

green(), which have the same functionality but are
pithier.

underline(), which have the same functionality

wrap(), which have the same functionality but are

fn whenever(&self, value: Condition) -> Painted<&T>

applies. Replaces any previous condition.

§Example
