Enhancements to checked_transaction/types.rs for Readability, Error Handling, and Maintainability

[Miska05]

Hello team,

While working with checked_transaction/types.rs, I observed a few opportunities for improvements that could boost the codebase’s quality:

1. Enhanced Readability: Comments and Documentation: Adding more inline comments explaining key sections would make the file more accessible, especially for contributors less familiar with the intricate transaction validation processes. Naming Conventions: Reviewing variable and function names for clarity would make it easier to understand their purpose at a glance.

2. Error Handling Improvements: Specific Error Messages: Currently, some error messages are generic. Making them more specific would improve debugging and provide users with clearer feedback. Custom Error Types: Introducing custom error types for critical areas could enhance control over error handling and make it easier to identify specific failure points.

3. Refactoring for Maintainability: Method Breakdown: Some methods could be broken down into smaller functions, each handling a specific task. This would improve code organization, making it simpler to manage and test. Modularization of Repeated Logic: Extracting repeated patterns into helper functions or separate modules could reduce redundancy and streamline updates.

4. Testing Enhancements: Additional Test Cases: Expanding tests to cover edge cases, particularly for error scenarios, would increase reliability. Documentation for Test Coverage: Clear documentation of the test cases and coverage areas could help new contributors quickly understand the testing scope.

Let me know your thoughts on these suggestions! I’m happy to work on implementing these changes if you feel they’d add value.
