rustup is the "rust native" way to setup rust: https://rustup.rs/

Some people here have both, Packaged rust for clean package builds and
some nightly version for testing newer features in development or such
things.

If you do not have rustc setup outside of Debian packages you can ignore
that.

Did you setup the devel repository?

deb http://download.proxmox.com/debian/devel buster main

And installed all build-dependencies? Maybe there are some missing in
d/control..

May want to ensure you have the proxmox crate installed: 

apt install librust-proxmox-dev librust-proxmox-api-macro-dev
