AWS Lambda adds support for Rust

AWS Lambda now supports building serverless applications using Rust. Previously, AWS classified Rust support in Lambda as ‘experimental’ and did not recommend using Rust for production workloads. With this launch, Rust support in Lambda is now Generally Available, backed by AWS Support and the Lambda SLA.

Rust is a popular programming language, offering high performance, memory efficiency, compile-time code safety features, and a mature package management and tooling ecosystem. This makes Rust an ideal choice for developers building performance-sensitive serverless applications. Developers can now build business-critical serverless applications in Rust and run them in Lambda, taking advantage of Lambda’s built-in event source integrations, fast scaling from zero, automatic patching, and usage-based pricing.

Lambda support for Rust is available in all AWS Regions, including the AWS GovCloud (US) Regions and the China Regions.
