The Rust Borrow Checker - A Deep Dive
summary
Explains how the Rust compiler stages (AST → HIR → MIR → LLVM) feed the borrow checker, shows MIR locals and spans, and demonstrates that the checker tracks initializations and moves and enforces that reference lifetimes cannot outlive their values. Uses cargo to show a moving-vs-borrowing example that initially errors, then changes y to a &x so the program prints "hi cloud native rust day" twice, and points to rustc diagnostics and the Guide to Rustc Development for fixes.
