At Rust Nation, Luciano Mammino delivered his talk; ‘Rust, Serverless, and AWS – Writing Lambdas in Rust’. As Rust continues to revolutionize the software engineering landscape, questions arise about its compatibility with serverless computing. Particularly in AWS, where it is not yet a natively supported runtime, the prospect may seem daunting – but Luciano is here to help.

This workshop on SERVERLESS RUST and AWS LAMBDA explored the convergence of Lambda’s flexibility and Rust’s performance. Discover why Rust stands out as the ideal choice for dominating this innovative and dynamic environment. Throughout the session, participants will embark on a journey from writing their first Lambda function, “Hello World,” using Rust to learning how to test it locally and deploy it into production.

During this session, Roberto Gambuzzi (@gbinside) and Luciano Mammino (@loige) delivered a pragmatic introduction to nom, a renowned Rust parser combinator crate.
