Changes Made

• Created src/asset.rs with:

  • DataKey enum (e.g., Asset(BytesN<32>)).

  • Asset struct with fields:

    • id, name, asset_type, category, branch_id, department_id, status,
      purchase_date, purchase_cost, current_value, warranty_expiry, stellar_token_id, owner.

• Implemented functions:

  • register_asset(...) → validates and registers a new asset.
  • get_asset(asset_id: BytesN<32>) → retrieves stored asset details.

• Integrated with types.rs for AssetType and AssetStatus.

• Used errors.rs for error handling (e.g., AssetAlreadyExists).

• Enforced access control with Address::require_auth().

• Added unit tests for registration and retrieval logic.

• Updated lib.rs to include asset.rs as a module.

How to Test

1. Build and deploy the Soroban contract.

2. Call register_asset with a unique asset ID and valid parameters.

   • Verify that the asset is stored on the ledger.

3. Call get_asset(asset_id) with the registered ID.

   • Ensure all stored details match the registration input.

4. Attempt to register an asset with a duplicate ID.

   • Verify that the contract returns AssetAlreadyExists error.

5. Attempt registration without required authorization.

   • Verify that the contract rejects the operation.

6. Run all unit tests → confirm they pass.
