Struct aws_sdk_iotdataplane::client::fluent_builders::GetRetainedMessage

pub struct GetRetainedMessage<C = DynConnector, M = DefaultMiddleware, R = Standard> { /* private fields */ }

Fluent builder constructing a request to GetRetainedMessage.

Gets the details of a single retained message for the specified topic.

This action returns the message payload of the retained message, which can incur messaging costs. To list only the topic names of the retained messages, call ListRetainedMessages.

Requires permission to access the GetRetainedMessage action.

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.

pub fn topic(self, input: impl Into<String>) -> Self

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.
