IAsyncRestPublisher¶

IAsyncRestPublisher is the client-side contract used to initiate RPC requests.

It provides a request/response abstraction built on top of RabbitMQ messaging.

Responsibilities¶

The publisher is responsible for:

creating requests;
serializing payloads;
publishing requests;
waiting for responses;
correlating responses.

Request Publication¶

The request publication process follows the same principles used by standard publishers.

Response Correlation¶

A response must be associated with the originating request.

Conceptually:

    Request --> CorrelationId

    CorrelationId --> Response

This allows multiple concurrent requests to be processed safely.

Formatter Integration¶

IAsyncRestPublisher relies on IDataFormatter for request serialization and response deserialization.

Error Handling¶

Typical failures include:

timeouts;
unavailable consumers;
transport failures;
serialization errors.

Applications should treat RPC calls as remote operations and design appropriate timeout and retry strategies.
