in case you (or someone else) wants to take a stab at it, here are 
backporting trees that have seen some production use as inspiration:

 https://git.proxmox.com/?p=cargo.git;a=shortlog;h=refs/heads/proxmox/buster
 https://git.proxmox.com/?p=rustc.git;a=shortlog;h=refs/heads/proxmox/buster
 https://git.proxmox.com/?p=dh-cargo.git;a=shortlog;h=refs/heads/proxmox/buster
 https://git.proxmox.com/?p=wasi-libc.git;a=shortlog;h=refs/heads/proxmox/buster
 https://git.proxmox.com/?p=llvm-toolchain.git;a=shortlog;h=refs/heads/proxmox/buster

note that for the first two, some points in the history are not 
backports in the strict sense, either because I imported the upstream 
version before Debian did and then pushed the result as MR for inclusion 
in Debian, or because it includes other feature MRs that have not yet 
been merged in Debian proper (like the rustftm and clippy changes in 
rustc atm).

generally speaking, backporting dh-cargo, wasi-libc and the required 
llvm-toolchain should allow a straight-forward backport of cargo and 
rustc.
