You mean like the USB Armory security key running Go bare metal?
I don't follow what you mean by that, care to elaborate?
That is a use case that many would assert should be written in C, yet F-Secure decided that given the security scenario, bare metal Go was the way.
Rust can't cover the enterprise use-cases of Go the same way that Go won't ever cover what Rust can do on systems/embedded level but there is enough overlap in some cases to confuse people into trying to compare them directly.
