Walkthrough

The changes in this pull request primarily focus on enhancing the handling of JSON and binary data types within the data type conversion logic. Key modifications include clearer distinctions between ConcreteDataType::Json and ConcreteDataType::Binary, improved conversion functions, and the introduction of new methods for JSON type handling. Additional changes involve refining error handling and updating import statements across various modules to utilize new utility functions for JSON processing.

🐇 In the meadow, hopping high,
JSON types now soar and fly.
With clearer paths and types defined,
Our data dances, well-aligned.
In code we trust, with joy we sing,
For every change, the rabbits bring! 🐰✨

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
