Interrupt edge minimum speed requirements?

Hi,
I'm currently thinking about anti-bounce for button inputs on my design and this brought me to the above question.
As I'd like to avoid adding an extra schmitt-trigger for cost reasons, I'm doing the anti-bounce using a simple RC low pass filter.

Does anybody know what the minimum rising (or falling) speed of the edge must be for it to be detected by the NVIC?
