Add 5 new comprehensive idioms to the Rust Idioms section, with focus on data engineering patterns: - Newtype Pattern: Type-safe wrappers for domain concepts, IDs, units, and validated data - RAII Guards: Resource management patterns for connections, files, transactions, and cleanup - Zero-Cost Abstractions: Iterator patterns, generics, and compiler optimizations for performance - Typestate Pattern: Compile-time state machine validation for pipelines and protocols - Error Handling Patterns: Idiomatic error handling with thiserror and anyhow Each idiom includes: - Comprehensive Vietnamese explanations - Real-world code examples relevant to data engineering - Best practices and anti-patterns - Performance considerations - When to use and when not to use These additions significantly expand the idioms section with patterns essential for building robust, performant data pipelines in Rust. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
…neous data Add detailed guide on "Sử dụng Enum để chứa nhiều loại dữ liệu" (Using Enums to contain multiple data types in Vec). Content includes: - Problem: Vec can only contain one type - Solution: Using Enums to wrap different types - Real-world examples for data engineering: - Spreadsheet cells with mixed types - Database rows with SqlValue enum - JSON-like data structures - Log events and metrics - Configuration values - Message queue events - Pattern matching and type-safe operations - Helper methods (as_*, to_*, is_*) - Best practices and when to use - Comparison with trait objects - Memory layout considerations The guide provides 10+ complete working examples showing how to handle heterogeneous data in a type-safe way, which is essential for data engineering tasks like: - Processing CSV/database rows with mixed column types - Handling JSON/configuration data - Building data pipelines with various data types - Logging and event systems All examples are practical, runnable, and focused on common data engineering scenarios. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
