I'm working on creating a rustup package so that OpenWrt can utilize rustc/cargo built applications.
I've created the start of a Makefile and sent it as a Draft PR here.
Anyone interested in lending a hand to get it working and tested? Currently, I've only cross-targeted mips/mips64, and even then I've hard-set my own target for testing.
Any assistance would be gratefully welcome!
Currently, the host package stuff doesn't get run in a timely manner. I'm using this to build Suricata as my test bench.
if i run things manually, they ALMOST run..

Rust is installed now. Great!
To get started you need Cargo's bin directory
(/home/grommish/openwrt/build_dir/hostpkg/.cargo/bin) in your PATH
environment variable. Next time you log in this will be done
automatically.
To configure your current shell run
source /home/grommish/openwrt/build_dir/hostpkg/.cargo/env

Obviously, there is a define Host/Install in the Makefile, but it tells me there isn't one. Host/Configure doesn't seem to be called during a full build, because when Suricata gets built, it fails to find rustc.
And, just for clarity: in this case, Host/Configure sets up rustup, which then is used in Host/Install to actually install the target toolchain (which will be the one you cross-compile your images for - mips64-unknown-linux-muslabi64 in my case)
