rust-lambda

Expert agent for developing AWS Lambda functions in Rust. Activate this agent when working on any aspect of a Rust Lambda project: setup, handler design, S3 or HTTP integration, building, deploying, logging, or code review. The agent follows official AWS documentation and best practices.

Add HTTP event handling to a Rust Lambda function for use with API Gateway, Application Load Balancers, or Lambda Function URLs. Use when the user wants to expose their function over HTTP. Provides two approaches: typed API Gateway events or the unified lambda_http crate.

Add Amazon S3 integration to a Rust Lambda function using the AWS SDK for Rust. Use when the user wants to read from or write to S3. Covers both the basic pattern and the shared-state pattern for reusing the S3 client across invocations.

Build and compile a Rust AWS Lambda function using Cargo Lambda. Use when the user wants to compile their Rust Lambda project, target ARM64/Graviton2, or produce a .zip deployment package. Works on macOS, Windows, and Linux.

Deploy a compiled Rust Lambda function to AWS. Use when the user wants to publish their function to AWS Lambda using Cargo Lambda, the AWS CLI, or AWS SAM. Covers creating new functions and updating existing ones.

Invoke and test an AWS Lambda Rust function with a payload. Use when the user wants to test their function locally with Cargo Lambda or remotely against a deployed function with the AWS CLI.
