Lambda triggered by SQS question

[Chandrian]

Hello,

I'm wondering how to manage the Records sent by the SQS service when it triggers a lambda function in Rust. In GO for example, I'm using the sqsEvent type, but could not find an equivalent for Rust. Could someone point me in the right direction?
I tried to define my own struct with a Vec, but since Message is from a different crate, I can't make it Deserialized.
Thank you

Hey @Chandrian !

We don't have an official crate with AWS Lambda events at the moment, but you can use the community-made aws_lambda_events one. It has an event type for SqsEvent: https://docs.rs/aws_lambda_events/0.5.0/aws_lambda_events/event/sqs/struct.SqsEvent.html

Thank you! Exactly what I was looking for

Are we meant to deserialize the body of the incoming HTTP request into this struct?

e.g. let event: SqsEvent = serde_json::from_slice(event.body().to_vec().as_slice()).unwrap();

[seanpianka]

Or, is creating a Lambda function that pulls from SQS instead of APIGW an "extension", and thus should be made with the lambda-extension crate (rather than lambda-http)?

@seanpianka I put an example here: #560

Thank you very much!

There is an example on how to handle SQS events in the examples directory:
