Please add an example for Rust lambda runtime

[brainstorm]

I would switch to this anytime (and away from serverless.com bloat) :)

there is now a makefile builder workflow that can be used directly. https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/building-custom-runtimes.html

Thanks much for the pointer @sriram-mv! I would totally endorse #174 from @softprops though, his PR makes integrating with AWS SAM effortless via Cargo (native Rust Makefile-equivalent).

More context into the "state of the SAM+lambda nation" in Rust for casual readers of this issue in case you are left wondering how to have a good SAM environment for Rust, hope it helps, I'll continue investigating how to put this thing together ;)

Current DX/UX issues: https://github.com/awslabs/aws-lambda-rust-runtime/pull/247/files#r488364611 ... and #174 (comment)
Interesting remote debugging architecture: https://github.com/rimutaka/lambda-debug-proxy

Nevermind, the AWS Rust team is doing a great job with cargo-lambda, SAM is not strictly needed anymore, AFAICT.
