Crate sayiir_macros 

Procedural macros for the Sayiir durable workflow engine.

Provides two macros that eliminate boilerplate when defining workflows:

• #[task] — Transforms an async function into a CoreTask struct with automatic registration, metadata, and dependency injection.

• workflow! — Builds a workflow pipeline with a concise DSL that desugars to WorkflowBuilder method calls.

Quick Example

use sayiir_macros::task;

#[task(timeout = "30s", retries = 3, backoff = "100ms")]
async fn charge(order: Order, #[inject] stripe: Arc<Stripe>) -> Result<Receipt, BoxError> {
    stripe.charge(&order).await
}

let workflow = workflow! {
    name: "order-process",
    codec: JsonCodec,
    steps: [
        validate(order: Order) { validate_order(order) },
        charge,
        (send_email || update_inventory),
        finalize,
    ]
};
