The privacy-apps components :

1. DVR types provide the necessary definitions for developers to interact with libdvr_client.so.

2. Client utils contain FFI helpers for working with DVR types.

The zkpass-demo components :

1. data_holder.rs: Handles the entire process, from generating tokens to verifying proofs.

2. data_issuer.rs: Manages the process of generating user data tokens.

3. proof_verifier.rs: Handles the generation of DVR tokens and the proof verification process.

4. lib_loader.rs: Contains the detailed logic for interacting with libdvr_client.so.
