Absolutely. It took me a few projects in Rust to sort of stumble on this and it can make some fairly complex business logic sit into nice matches that are trivial to run through.

What would be the equivalent of these patterns in Go?

You can't do the exact same thing in Go because Go doesn't have a way to define a sum type yet outside of generic constraints. The closest you can get is using an interface and a type switch but that won't give you exhaustive matching.
