AWS Lambda now fully supports Rust, moving from experimental to generally available status. This allows developers to create serverless applications using Rust, benefiting from its high performance, memory safety, and developer-friendly features. The article provides guidance on building and deploying Lambda functions in Rust using Cargo Lambda, a third-party tool designed to streamline this process. It outlines prerequisites, including having an AWS account, AWS CLI, Rust (version 1.70 or later), Node.js (20 or later), and AWS CDK installed. The article details the steps to create an HTTP-based Lambda function. It explains how to set up the project structure, including key files like `main.rs` and `http_handler.rs`. Key elements include handling incoming events, which can vary based on the service triggering the function, and using the `lambda_http` crate for responses. Logging is integrated with Rust's tracing libraries, allowing for structured logging to Amazon CloudWatch. Developers can test their functions locally before deploying them to AWS, using either the `cargo lambda` command or a `curl` request to the local emulator. For deployment, the article guides users through building the function and deploying it to AWS. It highlights the use of AWS CDK to create a serverless API in front of the Rust Lambda function, emphasizing best practices around security for the API Gateway. The process involves creating a new CDK project, updating the stack to include both the Lambda function and API Gateway, and deploying the stack. After deployment, users can test their API using the provided URL. The article concludes by pointing to additional resources for further learning on Rust and serverless application development.
