Rust: think about (and list) domains that the course applies to

[brson]

It's been suggested to me that, to be applicable to a wide audience, I should actually list a variety of domains that the knowledge in this course does or should apply to. Obviously databases is one, but it would be good to have 8 or 10 types of software that the content of the course can be applied to.

Some quick ideas:

• databases
• distributed systems
• microservices
• CLIs
• web services

Other ideas?
