Struct zebra_test::mock_service::ResponseSender[][src]

pub struct ResponseSender<Request, Response, Error> {
    request: Request,
    response_sender: Sender<Result<Response, Error>>,
}
Expand description

A helper type for responding to incoming requests.

An instance of this type is created for each request received by the MockService. It contains the received request and a [oneshot::Sender] that can be used to respond to the request.

If a response is not sent, the channel is closed and a BoxError is returned by the service to the caller that sent the request.

Fields

request: Requestresponse_sender: Sender<Result<Response, Error>>

Implementations

Create a ResponseSender for a given request.

Access the request that’s awaiting a response.

Respond to the request using a fixed response value.

The response can be of the Response type or a Result. This allows sending an error representing an error while processing the request.

This method takes ownership of the ResponseSender so that only one response can be sent.

If respond or respond_with are not called, the caller will panic.

Example
// Mock a service with a `String` as the service `Error` type.
let mut mock_service: MockService<_, _, _, String> =
    MockService::build().for_unit_tests();

mock_service
    .expect_request(1)
    .await
    .respond("Received one".to_owned());

mock_service
    .expect_request(1)
    .await
    .respond(Err("Duplicate request"));

Respond to the request by calculating a value from the request.

The response can be of the Response type or a Result. This allows sending an error representing an error while processing the request.

This method takes ownership of the ResponseSender so that only one response can be sent.

If respond or respond_with are not called, the caller will panic.

Example
// Mock a service with a `String` as the service `Error` type.
let mut mock_service: MockService<_, _, _, String> =
    MockService::build().for_unit_tests();

mock_service
    .expect_request(1)
    .await
    .respond_with(|req| format!("Received: {}", req));

mock_service
    .expect_request(1)
    .await
    .respond_with(|req| Err(format!("Duplicate request: {}", req)));
