Implement logic for campaign creation

[0xdevcollins]

Overview

This issue is to implement the core logic for campaign creation in our smart contract. The function create_campaign in contracts/boundless/src/logic/campaign.rs currently has a placeholder and needs a complete implementation according to the provided requirements.

Background

Our platform, as described in the README, relies on a robust and secure implementation of smart contracts to manage key functionalities, including campaign management. The Campaign struct in contracts/boundless/src/datatypes.rs and the CampaignManagement trait in contracts/boundless/src/interface.rs have already been defined. The logic needs to:

• Generate a unique campaign ID
• Create a new Campaign struct with a status of Status::Active
• Store the campaign in persistent storage
• Return the campaign ID

Requirements

• Location: Implementation should be done in contracts/boundless/src/logic/campaign.rs within the create_campaign function.

• Steps to Implement:

  1. Ensure the user (campaign owner) is authenticated by using owner.require_auth().
  2. Generate a unique campaign ID. Consider ways to ensure uniqueness (e.g., based on a counter or timestamp).
  3. Instantiate a Campaign struct with the following fields:
     • id: the newly generated unique ID
     • owner: provided owner address
     • title: provided title
     • description: provided description
     • funding_goal: provided funding goal (goal)
     • escrow_contract_id: provided escrow contract ID
     • milestones: provided milestones
     • backers: should be empty upon creation
     • status: set to Status::Active
  4. Store the campaign object in persistent storage.
  5. Return the campaign ID as the result

Technical Considerations

• Ensure error handling aligns with the project standards. If any step fails, return a proper BoundlessError.
• Verify the uniqueness of campaign IDs to avoid conflicts.
• Maintain code readability and adhere to the coding style outlined in the repository.

Acceptance Criteria

• The create_campaign function generates a unique campaign ID.
• A new campaign is instantiated with all provided and required attributes, especially with the status set to Active.
• The campaign is successfully stored in persistent storage.
• The function returns the correct campaign ID upon successful execution.
• Proper error handling is implemented for failure scenarios.
