Module ext 

Extensions for the customizability on usage of Step.

Optional enhancements that add runtime flexibility to static pipelines.

Conditional Decorators

The DecoratorExt trait provides some extensions that make the world easier

.when()

allowing decorators to be conditionally applied based on input predicates. This maintains the zero-cost property - conditions are evaluated inline without dynamic dispatch.

The condition check becomes part of the generated machine code, with no additional abstraction layers.

// The pipeline will never be executed due to the invalidity of the condition passed in.
let builder = Builder {val: 2}
                .step(ConditionalLongProcessing.when(|_| false));
