Rust runtime for Lambda with the CDK

This is a CDK project that deploys a Rust function using the Rust runtime for Lambda. This creates a basic handler that logs some data sent as input.

Update: I have updated the Lambda function to use the newly introduced Graviton Processor for faster and cheaper workloads.

Prerequisites

• Follow instructions mentioned in this post that explains how to build Rust functions for AWS Lambda.

Note: As we are using arm as the architecture, we need to add the following target:

rustup target add aarch64-unknown-linux-musl

And then follow the instructions as specified in this post for cross-compilation.

• Create a cdk.context.json with the region key to specify the region of your choice (default is us-east-2).

{
  "region": "us-east-1"
}

The cdk.json file tells the CDK Toolkit how to execute your app.

Useful commands

• yarn build compile typescript to js
• yarn watch watch for changes and compile
• yarn test perform the jest unit tests
• yarn deploy deploy this stack to your default AWS account/region
• yarn cdk diff compare deployed stack with current state
• yarn cdk synth emits the synthesized CloudFormation template
