AWS Lambda Officially Rust: From Scratch to Progressive Bindings
summary
AWS Lambda now officially supports Rust; the talk shows building and deploying a Rust Lambda from scratch using Cargo Lambda and highlights Rust’s performance and tooling. It also covers progressive integration of Rust into existing Lambdas via language bindings — PyO3 for Python, napi-rs for JavaScript, JNI for Java/Kotlin and csbindgen for C# — to speed critical parts without a full rewrite.
