I naively (!) began exploring JSON marshaling of Protobufs in rust. Other protobuf language SDKs include JSON marshaling making the process straightforward. I was to learn that, in rust, it’s not so simple. Unfortunately, for me, this continues to discourage my further use of rust (rust is just hard). My goal was to marshal an arbitrary protocol buffer message that included a oneof feature. I was unable to JSON marshal the rust generated by tonic for such a message.

I’ve begun exploring Vultr after the company announced a managed Kubernetes offering Vultr Kubernetes Engine (VKE). In my brief experience, it’s a decent platform and its CLI vultr-cli is mostly (!) good. The CLI has a limitation in that command output is text formatted and this makes it challenging to parse the output when scripting. NOTE The Vultr developers have a branch rewrite that includes a solution to this problem.
