This looks along the same lines as CyberEther, though CyberEther does have alot more features to enable massive compute of raw data and arguably nicer gui.(https://github.com/luigifcruz/CyberEther)
In general, any llvm compiled language is going to have persistent unpredictable jitter related issues. Only the naive think Rust is a replacement for C/C++, but the same issues also occur with clang compilers for the same reasons.
They now have 2 DSP problems by porting to llvm languages like Rust, but will insist their work isn't worse than the C they attempted to "upgrade". =3
I wonder how much of the signal graph feature set could be implemented as an SDR++ module. It could even be written in Rust with some FFI.
Rather than rewrite the entire SDR++ core in a separate project, maybe it would be better to incrementally port the existing code to Rust in a fork. I don't know what attitude the maintainers have toward Rust, though.
