Organize code to maximize readability and maintainability. When code becomes complex, break it down into smaller, more manageable pieces with clear responsibilities: 1. **Place initialization logic in constructors**: Ensure objects are always in a valid state by initializing them fully in constructors rather than requiring separate initialization methods. ```rust // Instead of: struct FilesystemLocks { root: PathBuf, } impl FilesystemLocks { fn from_path(root: impl Into) -> Self { Self { root: root.into() } } fn init(self) -> Result { // Initialize here... } } // Prefer: struct FilesystemLocks { root: PathBuf, } impl FilesystemLocks { fn from_path(root: impl Into) -> Result { let this = Self { root: root.into() }; // Initialize here... Ok(this) } } ``` 2. **Extract complex expressions**: Assign complex expressions to named variables outside of nested structures to clarify their purpose and make code flow easier to follow. 3. **Create dedicated types**: When functionality around a concept grows complex, consider creating a dedicated type to encapsulate that logic and provide a cleaner interface. 4. **Combine related implementations**: Keep related functionality together by avoiding multiple separate `impl` blocks for the same type when they're logically connected. Following these principles leads to code that is easier to understand, maintain, and extend.
