trigger: Decouple Trigger from clap #2864
Conversation
There was a problem hiding this comment.
In general I'm in favor of reducing the number of dependencies an implementor has to explicitly depend on especially if the implementor doesn't really have a choice.
I do feel though like we've long been on a path of exposing dependencies just when we run into a place where it would be convenient. This doesn't feel particularly disciplined, and I worry that over time we're going to regret some of these decisions.
I'm not necessarily against merging this as is, so I'll approve the PR, but I wanted to voice my concern that I'm not convinced this is the right path forward.

I don't love making clap even more a part of the Spin public API, but alas it may be too late...

Another option would be to rename Trigger::CliArgs to e.g. ::GlobalConfig and move the Args constraint to FactorsTriggerCommand ... T::GlobalConfig: Args (and RuntimeFactorsBuilder? 🤔)

I'm surprised by this. I looked at a few of the external triggers, and they don't use Linker. Is this really necessary?

Its used in the (admittedly optional) Trigger::add_to_linker signature.
