hardening problem and not package upload permission

[Nilson Silva <nilsonfsilva@hotmail.com>]

Hello guys!
This is my first package in Rust that I am delivering to the care of the team.
But I have two situations:
Can someone help me?

1. Is there any flag we put in debian/rules to solve the protection issue: hardening-no-fortify-functions

2. following these steps here, https://blog.hackeriet.no/packaging-a-rust-project-for-debian/

I can't push, it's showing this message saying no write permission:

Remote: ================================================ === === =============================
remote control:
remote: You don't have permission to submit code for this project.
remote control:
Remote: ================================================ === === =============================
remote control:
fatal: Unable to read from remote repository.

Make sure you have the correct access rights.
and the repository exists.

thank you
