Enum CompiledStep 

pub enum CompiledStep {
    Process {
        processor: BoxProcessor,
        body_contract: Option<BodyType>,
        lifecycle: Option<Arc<dyn StepLifecycle>>,
    },
    Stop,
    Segment {
        segment: OutcomeSegment,
        body_contract: Option<BodyType>,
        lifecycle: Option<Vec<Arc<dyn StepLifecycle>>>,
    },
}

A compiled pipeline step.

Process is the normal case: a boxed processor plus its optional body contract. Stop (added in Task 3b) is the Stop EIP marker — run_steps recognises it and produces PipelineOutcome::Stopped without invoking a Tower service. Segment (added in Task 3) wraps an OutcomeSegment for structural EIPs with outcome-aware sub-pipelines.

Boundary: CompiledStep is the compile-time representation. At runtime, run_steps consumes a Vec<CompiledStep> (Stop variants included) and produces a PipelineOutcome; the wrapping Service<Exchange> impl translates PipelineOutcome back to Result<Exchange, CamelError>. See ADR-0024.

Variants

Process

Fields

processor: BoxProcessor

body_contract: Option<BodyType>

lifecycle: Option<Arc<dyn StepLifecycle>>

Lifecycle handle for this processor, if it is stateful. None for stateless processors (the common case).

Stop

Stop EIP marker. run_steps produces PipelineOutcome::Stopped(ex) without invoking a Tower service. Replaces StopService (Task 7).

Segment

Outcome-aware structural EIP segment. run_steps invokes segment.run(ex) and matches on the returned PipelineOutcome. See ADR-0025.

Fields

segment: OutcomeSegment

body_contract: Option<BodyType>

lifecycle: Option<Vec<Arc<dyn StepLifecycle>>>

Lifecycle handles from children nested inside this segment. Option<Vec<...>> (not Option<Arc<...>>) so multiple stateful children (e.g. Idempotent+Resequencer inside Filter) each register independently.
