My first encounter will likely be the opposite, i.e. a call that will only produce a Result::Err if anything, and never a Result:Ok. I've made programs where there are a bunch of continuously running jobs that should never terminate in the happy scenario. If any of these jobs terminate, it'll be due to some sort of failure, and so Result<!, MyError> seems like a reasonable return type for such job. I think I've already used the Infallible in there but I think this being part of the language now makes the code feel more correct or clean or something like that.
