Parking Lot Management Smart Contract Overview

The parkinglot::parkinglot module is a smart contract written in the Move programming language, designed to manage a decentralized parking lot system. This contract includes functionalities for managing parking slots, processing payments, and system administration.

Purpose

The primary purpose of this module is to create a transparent and efficient parking lot management system on a decentralized platform. It aims to ensure fair management of parking slots, accurate tracking of parking durations, and proper handling of payments and revenue.

Features

• Slot Management: Allows administrators to create and manage parking slots.
• Slot Reservation and Usage: Enables users to reserve, occupy, and vacate parking slots.
• Payment Processing: Facilitates the creation of payment records and calculation of parking fees.
• Revenue Management: Allows administrators to withdraw and distribute revenue generated by the parking lot.

Structs

• Slot: Represents a parking slot, including a unique ID, status, start time, and end time.
• ParkingLot: Represents a parking lot, including a unique ID, admin address, list of parking slots, and SUI token balance.
• PaymentRecord: Represents a payment record, including a unique ID, amount, and payment time.
• AdminCap: Represents administrator capabilities, including a unique ID and admin address.

Functions

• init: Initializes the contract by setting up the administrator and parking lot.
• create_slot: Allows administrators to create a new parking slot.
• reserve_slot: Reserves a parking slot by setting its status to occupied.
• enter_slot: Occupies a parking slot and records the start time.
• exit_slot: Vacates a parking slot and records the end time.
• create_payment_record: Creates a payment record.
• calculate_parking_fee: Calculates the parking fee.
• withdraw_profits: Withdraws profits from the parking lot (ensures the caller is an administrator).
• distribute_profits: Distributes profits of the parking lot.
• test_generate_slots: Function for testing slot generation.

Deployment and Testing Instructions

Deployment

1. Prerequisites: Ensure that all necessary tools and dependencies are installed as per the setup instructions mentioned.
2. Build Package: Use the command sui move build to build the package.
3. Publish Package: Publish the package using the command sui client publish --gas-budget 100000000 --json. Extract the package ID and other necessary information from the output.
4. Configure Connectivity: Run sui client active-address and provide details such as node URL and configuration name to configure connectivity to the local node.
5. Get Tokens: Obtain SUI tokens for testing using the appropriate command (curl or sui client faucet).
6. Switch to Testnet: If testing on the testnet, switch to the testnet environment using sui client switch --env testnet.
7. Deploy Contract: Deploy the smart contract to the desired environment using the extracted package ID and other relevant information.

Testing

1. Unit Testing: Run unit tests using the command sui move test.
2. Manual Testing: Interact manually with the deployed contract using CLI commands provided in the contract documentation. Test various functionalities such as creating parking slots, reserving slots, handling payments, and managing revenue.
3. Integration Testing: Conduct integration testing by simulating real-world scenarios and ensure that the contract behaves as expected under different conditions.
4. Error Handling: Test error handling mechanisms by intentionally triggering error conditions and verify that the contract responds with the correct error codes.
5. Gas Usage: Monitor gas usage during testing to ensure that the contract operates within acceptable gas limits and does not exceed the specified gas budget.
6. Security Audit: Consider performing a security audit to identify and address potential vulnerabilities in the contract code.
7. Feedback and Iteration: Gather feedback from testing and iterate on contract design and implementation as needed to enhance functionality, performance, and security.
