Implementations

impl<C, M, R> GetRetainedMessage<C, M, R> where
    C: SmithyConnector,
    M: SmithyMiddleware<C>,
    R: NewRequestPolicy, 

pub async fn send(
    self
) -> Result<GetRetainedMessageOutput, SdkError<GetRetainedMessageError>> where
    R::Policy: SmithyRetryPolicy<GetRetainedMessageInputOperationOutputAlias, GetRetainedMessageOutput, GetRetainedMessageError, GetRetainedMessageInputOperationRetryAlias>, 

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

The topic name of the retained message to retrieve.

pub fn set_topic(self, input: Option<String>) -> Self

The topic name of the retained message to retrieve.
