Edge displacement

How can I create this effect in Blender?

Probably with the Fracture modifier:

I’m using Cell Fracture addon for 2.8+ to break things. My understanding is, all fracturers will create somewhat simple geometry and if you do more detailed slice-up, it’s going to become very heavy and still won’t be as refined, as the kind of details micro displacement can give. This seems to be true for any 3D program. I’m looking for a material solution, where I can displace just “on the edges” and leave the original surface intact.
