Module exchange 

Structs

Exchange

An Exchange represents a message being routed through the framework.

Enums

ExchangePattern

The exchange pattern (fire-and-forget or request-reply).

Constants

CAMEL_STOP

Pipeline-executor-recognized stop signal. Set by processors (ThrottleStrategy::Drop, SamplingService) that cannot return PipelineOutcome::Stopped directly because they are Tower Service (Process mode), not OutcomePipeline (Segment). The executor checks this after each step completion. See ADR-0024 amendment.

ORIGINAL_MESSAGE_EXTENSION

Extension key used by use_original_message: stashes the pre-route Message so the error handler can restore body+headers before DLC dispatch.

PROPERTY_EXCEPTION_CAUGHT

Property key for the caught exception (Java Camel parity alias).

PROPERTY_EXCEPTION_HANDLED

Property key set when an exception has been handled (Java Camel parity).

PROPERTY_EXCEPTION_KIND

Property key for the exception kind (error variant name via classify()).

PROPERTY_EXCEPTION_MESSAGE

Property key for the exception message (error Display string).

Functions

is_camel_stop

Check whether the exchange carries the CamelStop signal.
