Enum EffectExecution 

pub enum EffectExecution {
    Plain,
    RouteMetrics {
        request_counter: Metric<u64, ()>,
        latency: Metric<Duration, ()>,
    },
    ServiceMetrics {
        latency: Metric<Duration, ()>,
        errors: Metric<u64, ()>,
    },
}

Execution mode for run_effect_from_state_with.

Using an enum makes illegal metric states unrepresentable: a plain run has no metrics, route metrics have request counter + latency, and service metrics have latency + errors.

Variants

Plain

No metrics; equivalent to run_effect_from_state.

RouteMetrics

Axum route metrics: increment a request counter and record handler latency.

Fields

request_counter: Metric<u64, ()>

Request counter incremented once per call.

latency: Metric<Duration, ()>

Latency histogram / timer / summary.

ServiceMetrics

Tower service metrics: record request latency and increment an error counter on failure.

Fields

latency: Metric<Duration, ()>

Latency histogram / timer / summary.

errors: Metric<u64, ()>

Error counter incremented when the effect returns Err.

Trait Implementations

impl Clone for EffectExecution

fn clone(&self) -> EffectExecution

Returns a duplicate of the value.

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

Performs copy-assignment from source.
