i am deploying a program written in rust and i keep getting the errors:
==> No open ports detected, continuing to scan…
==> Docs on specifying a port: https://render.com/docs/web-services#port-binding
==> Port scan timeout reached, no open ports detected. Bind your service to at least one port. If you don’t need to receive traffic on any port, create a background worker instead.

i have already made a PORT environment variable and set it to 8080. i don’t have anything in my rust scripts that is related to http requests, so how would i add that
