The bond between the two carbon atoms is covalent. However, the bond between calcium and the CX2X2− C X 2 X 2 − fragment is ionic. Therefore, calcium carbide can be classified as an ionic compound. If you dig deeper, you may come across the crystal structure of calcium carbide; see for example the following taken from Wikipedia:
Polymorphic CaC2 was prepared by reacting mixtures of CaH2 and graphite with molar ratios between 1:1.8 and 1:2.2 at temperatures between 700 and 1400 °C under dynamic vacuum. These conditions ...

PMID: 36638245. DOI: 10.1590/2175-8239-JBN-2022-0101en. Abstract. Introduction: Artificial fruit ripening agents such as ethanol, ethylene, ethephon, and calcium carbide (CaC2) is usually employed in stimulating the fruit ripening process.
The entire CAC2 cDNA sequence was expressed in Escherichia coli and the resulting recombinant biotin carboxylase was enzymatically active in carboxylating free biotin. The catalytic properties of the recombinant biotin carboxylase indicate that the activity of the heteromeric ACCase may be regulated by light-/dark-induced changes in stromal pH.
Calcium carbide with water yields acetylene. Decomposing of 30% Peroxide in water is catalyzed by grainy stuff like CaC2. Combine both of them: generating C2H2 + O2 at the same time. Putting CaC2 in a plastic bottle containing 30% H2O2 and closing it will result in a HEAVY EXPLOSION.
