We love open-source software, and use the following in the New Relic Lambda Extension (Rust). Thank you, open-source community, for making these fine tools! Some of these are listed under multiple software licenses, and in that case we have listed the license we've chosen to use.

The source code and full third-party notices are also available in the [GitHub repository](https://github.com/newrelic/newrelic-lambda-extension-rust).
