💫 Advanced Features

Zero-Copy Block Processing

The system uses Zig's comptime features to generate zero-copy parsers, allowing direct processing of network buffers without intermediate allocations.

Memory Management

• Preallocated buffer pools
• Arena allocators for batch processing
• Comptime memory optimization
• Zero heap allocations in hot paths

Error Handling

• Automatic reconnection with exponential backoff
• Comprehensive error reporting
• Graceful degradation under load
• Self-healing connection management
