Module lambda 

A wrapper around the lambda_runtime crate.

This wrapper provides wrappers to make it easier to write Lambda functions which consume messages from various events, such as an SQS queue configured with an event source mapping, or a step function. It also provides mechanisms for running message handlers locally, without the full AWS Lambda environment.

Structs

S3Event

S3Event which wrap an array of S3EventRecord

SqsEvent

Re-export from aws_lambda_events::event::sqs::SqsEvent, with RunnableEventType implemented. The Event sent to Lambda from SQS. Contains 1 or more individual SQS Messages

Traits

LambdaContext

A trait of the Context type, required when using run_message_handler to execute the message handler.

LocalContext

A trait of the Context type, required when using run_local_handler to execute the message handler.

RunnableEventType

A trait that allows a type to be used as the EventType trait of a LambdaContext.

StepFunctionEvent

The StepFunctionEvent trait allows any deserializable struct to be used as the EventType for a LambdaContext.

Functions

run_local_handler

Executes a message handler against the message provided by the LocalContext.

run_message_handler

Executes a message handler against all the messages received in a batch from an SQS event source mapping.

running_on_lambda

Determine whether the code is being executed within an AWS Lambda.

Type Aliases

Error

Re-export of lambda_runtime::Error.
