The Go code in K8s is simple, the system of Kubernetes is complex
Rust isn’t about machismo, it’s about high performance computing. Try writing graphics or machine learning code in Go, it’s not about being tough it’s about having a tool that can actually do the job.
And zero runtime cost abstractions. And having a non-profit to shepherd the project (and thereby having a good chance that you may influence the project). And strong typesafety. And design by committee (see how async-await was "agreed" upon).
Also Rust is called a multi-paradigm prog lang in the article: I dont think so. Scala is. Rust is not. It brings as much FP features into the language without sacrificing its core paradigm: an imperative systems language.
Yes. That's what I said. So, advocating for Rust in a non-high-perf requirement project makes for extra effort/optimization where it is not needed. Speed of dev, correctness, ease of maintenance are needed though. Optimizing for the sexy rather than the needed is a textbook machismo attitude. Good for CV-builders and for ego maybe but it usually hurts the company and the maintainers down the road.
Can you link me to a doc which explains the runtime scheme type system of Kubernetes? Could never wrap my head around how that even works. And why they had to even do this in the first place?
Because they wanted stuff like Watcher<T>, but Go does not have generics.
Runtime scheme and the k8s machinery can be pretty awkward. Scheme is just a way of registering the available datatypes by group/version/kind so the client can look at any given object and figure out if it knows how to decode it.
