I am running Rust code on AWS Lambda on arm64 architecture which is part of a larger program itself.

Basically I have a x86_64 binary that I do not have source code for and I include it in my final .zip lambda by using:

[package.metadata.lambda.build]
include = ["...path-to-binary"]

I need this binary to process parts of a temp file that is created during lambda execution. Is there any way to use lambda layers to achieve this? The docs mention the layers have to be same but couldn’t the output just be read using some Endianness parser.
