I want to declare a singleton of a particular type, which is generic. I only need to produce an instance for one particular value of that generic type (which is convenient since I don't believe Koin lets me differentiate on that anyway).

So I can do

single {
  GraphQLServer<ApplicationRequest>(get(), get(), get())
}

But I do like the constructor DSL. Is it possible to do this with singleOf? singleOf(::GraphQLServer) says it doesn't have enough information to infer a type, and singleOf(::GraphQLServer<ApplicationRequest>) isn't even valid syntax.

did you tried singleOf<GraphQLServer<ApplicationRequest>>(::GraphQLServer)?

I'm afraid it won't have enough generic info else 🤔

I thought I did and it didn't work, though I can try again. (Just using single has been working fine

[David Glasser]

gives an enormous screen-filling error

yeah sure
