Docs: Enhanced Comments for Structs and Functions

[hackerzgz]

Improve the code documentation in the repository. By adding comprehensive comments to each struct and function, we can enhance the codebase's readability and maintainability.

Key Changes:

• Thoroughly reviewed and expanded comments for all relevant structs
• Meticulously documented each function, including purpose, parameters, and return values
• Provided detailed descriptions where necessary for context and clarity
• Added runnable code examples within the core functions to demonstrate their usage.
