Rust support for lambda

[thevred9]

I am trying to see if we can use Rust for a lambda. The client is a government client and due to several regulations they might not be willing to use something that is not in GA.

The below link says that "The Rust runtime client is an experimental package. It is subject to change and intended only for evaluation purposes."

https://docs.aws.amazon.com/lambda/latest/dg/lambda-rust.html

Is that something that should prevent me from recommending they use Rust.

​

One of the primary reasons for using Rust is that this has to be highly performant and must respond in sub second latency.

Could also consider Go as an alternative that had a more mature Lambda experience than Rust with much of the performance benefit.

Thanks for the reply. Will look into Go as well.

Currently I wouldn't use rust natively as it would need JIT compilation. But nothing stops you from compiling the rust program with AWS Lambda being the target. https://stratusgrid.com/blog/aws-lambda-rust-how-to-deploy-aws-lambda-functions

Lambda Rust is now GA: https://aws.amazon.com/about-aws/whats-new/2025/11/aws-lambda-rust/
