By: Dingkun Yang
Posted:

This project demonstrates a simple AWS Lambda function written in Rust using the lambda_runtime crate.

Overview

The Lambda function takes an input data structure, processes it, and returns an output data structure.

  • Input Data Structure: InputData
  • Output Data Structure: OutputData

Invoke the Lambda function

Deploy to AWS Lambda

Deploy to AWS

Note: Due to billing and security reasons, only IAM user can access the above link. You may need to deploy the lambda function to your AWS account manually.

Requirements

  • Rust (https://www.rust-lang.org/)
  • cargo-lambda (https://www.cargo-lambda.info/guide/getting-started.html)
  • AWS CLI configured with appropriate permissions

Setup

  1. Clone this repository:

    git clone [email protected]:Yer1k/cargo_lambda.git

  2. Navigate to the project directory:

    cd lambda_function

  3. Build the Lambda function:

    cargo lambda build --release

  4. Deploy the Lambda function to AWS:

    cargo lambda deploy --region <AWS_REGION>

    Replace <AWS_REGION> with your desired AWS region.

Usage

Once deployed, you can invoke the Lambda function using the AWS Management Console, AWS CLI, or AWS SDKs. The function expects input data in the format specified by the InputData struct and returns output data in the format specified by the OutputData struct.

Testing

You can test the Lambda function locally using the cargo-lambda tool or by setting up a local development environment. For testing purposes, you can modify the handler function in src/main.rs to simulate different input scenarios and observe the output.
