bind.toInstance() vs @Singleton

[Aleksey Matsarski]

What is the difference between bind.toInstance() and @Singleton? Will be the result - singleton for both? 

[Laszlo Ferenczi]

The difference is who instantiates the class. 

@Singleton will be guice instantiated (and therefore can participate in AOP for example), toInstance() expects an instance which is already created, AOP is not possible for this type of binding.

And constructor injection isn't possible for toInstance()
