Maintain code organization by keeping files focused on a single responsibility and splitting large files into smaller, well-organized modules. This improves code navigation, readability, and maintainability. Key guidelines: 1. Move code to dedicated files when it represents a distinct functionality 2. Split large files (>500 lines) into logical modules 3. Place related functionality in the same module 4. Use clear, descriptive file names that reflect the content Example of good organization: ```rust // Instead of putting everything in mod.rs: // src/binary/mod.rs mod local_proxy; // Move to separate file pub use local_proxy::*; // src/binary/local_proxy.rs pub struct LocalProxy { // Implementation details } // Instead of one large compute.rs: // src/compute/mod.rs mod core; // Core compute functionality mod prewarm; // Prewarm-specific implementations mod helpers; // Helper functions pub use core::ComputeNode; ``` This approach: - Makes code easier to navigate and maintain - Reduces cognitive load when working with the codebase - Facilitates code review and testing - Improves module cohesion
