The Rust borrow checker is refusing my code. Explain what I'm actually asking the compiler to prove and fix it. Compiler error: The code: What I'm trying to model in ownership terms: [DESCRIBE] Give me: 1. The error in one sentence — no borrow checker lore, just what's unsound about my code 2. Which of these I'm hitting: Two mutable borrows overlapping Mutable borrow while an immutable one lives Returning a reference to a local Self referential struct Iterator invalidation Lifetime elision picking the wrong lifetime 3. The idiomatic fix — split borrows / RefCell (only if truly needed) / owned data / Rc+RefCell / Arc+Mutex / restructure so ownership flows one way 4. Which option to REJECT and why (unsafe, Box::leak, cloning everything) 5. The one line explanation of the ownership shape that WILL compile — so I recognize it next time
