How does it deal with GC pauses? Wouldn't they introduce unacceptable jitter for this kind of application?

Anyway, it's relatively straightforward to rewrite from Go to Rust if you aren't doing things that essentially rely on GC (which is quite rare).

A PLC controller deals with anything that requires tight timing, so the Go portion is mostly higher-level control of the system and states.

Go’s GC is pretty snappy these days, but I don’t think it’s that snappy. :)
