Can someone share a snippet of using typed qualifiers in koin? i don't see any documentations on it and everything i'm trying so far isn't working.
Left image is what i'm trying to do in my module, and right image is the site of injection but I get no definition exceptions.

I think it’s missing declaration for AddDiaryUseCase, so something like this:

fun useCaseModule() = module {
    singleOf(::LocalDataSource) {
        bind<DataSource>()
        named<LocalDataSourceQualifier>()
    }
    singleOf(::RemoteDataSource) {
        bind<DataSource>()
        named<RemoteDataSourceQualifier>()
    }
    single {
        AddDiaryUseCase(get(named<LocalDataSourceQualifier>()), get(), get())
    }
}

but if you need different AddDiaryUseCase instance based on DataSource type, probably it’s better like this:

fun useCaseModule() = module {
    singleOf(::LocalDataSource) {
        bind<DataSource>()
    }
    singleOf(::RemoteDataSource) {
        bind<DataSource>()
    }
    single(named<LocalDataSource>()) {
        AddDiaryUseCase(get<LocalDataSource>(), get(), get())
    }
    single(named<RemoteDataSource>()) {
        AddDiaryUseCase(get<RemoteDataSource>(), get(), get())
    }
}

and you can later get/inject it with get(named<LocalDataSource>()) or inject(named<RemoteDataSource>()), so you wont need LocalDataSourceQualifier and RemoteDataSourceQualifier
