when using workers, does cloudflare have to have access to your source code?

It seems to push to workers, you have to give cloudflare access to github to get the code into the system.
Is it possible for me to compile my worker locally, and push the binary? (Say I am using rust)

Workers Builds is optional. You can install wrangler locally and use wrangler deploy and all that, and you'd just be pushing the built version of your script
