Thanks. I'll take a look. But it being in Rust makes me a bit hesitant. A lot of these projects in Rust seem to fizzle out as soon as people get bored with them once they become hard.

Do you know of anything major that's using it?

GUI frameworks in any language often fizzle out when they become hard. Its probably one of the larger cases of devs not knowing the massive undertaking they’re embarking on when they start.
