Struct aws_sdk_lambda::client::fluent_builders::UpdateEventSourceMapping

pub struct UpdateEventSourceMapping { /* private fields */ }

Fluent builder constructing a request to UpdateEventSourceMapping.

Updates an event source mapping. You can change the function that Lambda invokes, or pause invocation and resume later from the same location.

For details about how to configure different event sources, see the following topics.

• Amazon DynamoDB Streams

• Amazon Kinesis

• Amazon SQS

• Amazon MQ and RabbitMQ

• Amazon MSK

• Apache Kafka

The following error handling options are only available for stream sources (DynamoDB and Kinesis):

• BisectBatchOnFunctionError - If the function returns an error, split the batch in two and retry.

• DestinationConfig - Send discarded records to an Amazon SQS queue or Amazon SNS topic.

• MaximumRecordAgeInSeconds - Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires

• MaximumRetryAttempts - Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

• ParallelizationFactor - Process multiple batches from each shard concurrently.

For information about which configuration parameters apply to each event source, see the following topics.

Implementations

impl UpdateEventSourceMapping

pub async fn send(
    self
) -> Result<UpdateEventSourceMappingOutput, SdkError<UpdateEventSourceMappingError>>

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 uuid(self, input: impl Into<String>) -> Self

The identifier of the event source mapping.

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

The identifier of the event source mapping.

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

The name of the Lambda function.

Name formats

• Function name - MyFunction.

• Function ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction.

• Version or Alias ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD.

• Partial ARN - 123456789012:function:MyFunction.

The length constraint applies only to the full ARN. If you specify only the function name, it's limited to 64 characters in length.

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

pub fn enabled(self, input: bool) -> Self

When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

Default: True
