Rust package devel repo - jiangcuo/Proxmox-Arm64 GitHub Wiki
Devel repo contains the source for the Rust crate needed by building proxmox rust packages.
Their names are of the form librust-xxxxx-dev.

These packages contains the source for the rust xxx crate,no binarys.
When repacked done, we can easy to solve proxmox-rust-packages depends (E.g. proxmox-apt,proxmox-backup-qemu) by using command mk-build-deps --install.
Debian devscripts will be reading debian/control file and auto-install depends.
Cargo will search crates in /usr/share/cargo/registry/ but not crates.io
We can easy download these by using apt-mirror ,then extract and replace amd64 in debian/control with arm64. Finally use command dpkg-deb -Zxz -b to archive new arm64 packages.
repack.sh is a simple script to repack .
Now, I have created a arm64 devel repo only contain rust packages.
