# Asap

This interface defines the helper methods around a Conan Asap

```typescript
export interface Asap<T> {
    catch(error: IConsumer<Error>): this;

    then(consumer: IConsumer<T>): this;

    onCancel(consumer: ICallback): this;

    map<Z>(mapper: IFunction<T, Z>): Asap<Z>;

    chain<Z>(chainProducer: IFunction<T, Asap<Z>>): Asap<Z>;

    type: AsapType;

    cancel(): boolean;
}
```
