Usage
require 'injected'
class DemoInterface < Injected::Interface
interface_method(:demo, :arg1, :arg2, arg3: :default)
end
class DemoImplementation < Injected::Implementation
implements DemoInterface
def demo(arg1, arg2, arg3: :default)
"arg1: #{arg1}; arg2: #{arg2}; arg3: #{arg3}"
end
end
class DemoService < Injected::Instance
injected(DemoInterface, :demo_dependency)
def demo
demo_dependency.demo(1, 2)
end
end
injector = Injected::Injector.new(
DemoInterface => DemoImplementation
)
demo_service = injector.instance(DemoService)
demo_service.demo #=> "arg1: 1; arg2: 2; arg3: default"
# inside demo_service
demo_interface.demo(1, 'two')
# => "arg1: 1; arg2: two; arg3: default"
demo_interface.demo(1, 'two', arg3: :three)
# => "arg1: 1; arg2: two; arg3: three"
