# Creating Lambda functions in the AWS SDK for Rust
<a name="lambda"></a>

For detailed documentation on developing AWS Lambda functions with the AWS SDK for Rust, see [Building Lambda functions with Rust](https://docs.aws.amazon.com/lambda/latest/dg/lambda-rust.html) in the *AWS Lambda Developer Guide*. That documentation guides you through using:
+ The Rust Lambda runtime client crate for core functionality, [https://github.com/awslabs/aws-lambda-rust-runtime](https://github.com/awslabs/aws-lambda-rust-runtime). 
+ The recommended command-line tool for deploying the Rust function binary to Lambda with [Cargo Lambda](https://www.cargo-lambda.info/guide/what-is-cargo-lambda.html). 

In addition to the guided examples that are in the *AWS Lambda Developer Guide*, there are also Lambda calculator example available in the [AWS SDK Code Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/rustv1/lambda) on GitHub.
