	Slices: []*protos.Assignment_Slice{
		{Start: 0x0, Replicas: []string{"a", "b"}},
		{Start: 0x3333333333333333, Replicas: []string{"a", "c"}},
		{Start: 0x6666666666666666, Replicas: []string{"b", "c"}},
		{Start: 0x9999999999999999, Replicas: []string{"a", "b", "c"}},
	},
	Version: 42,
}
fmt.Println(FormatAssignment(assignment))
