Difference between Navigation overlay and Toggle navigation in Web Design

Writnig task about Responsive navigation, school obligations. So I found on internet that Responsive navigation patterns could be devide as: Responsive Navigation • Toggle or multi-toggle pattern • Footer anchor pattern • Navigation overlay pattern • Slide-in/slide-out pattern • Vertical stacking pattern • -drop-down pattern • “Transformer tabs” pattern • Off-canvas-navigation

Now, I can't find real difference between •Navigation overlay pattern and •Toggle pattern. Anyone?
