How does MIR enable Rust’s borrow checker to scale efficiently?
Updated May 24, 2026
Short answer
MIR simplifies control flow, making borrow analysis tractable and scalable.
Deep explanation
MIR removes syntactic complexity and expresses code in a structured control-flow graph. This allows the borrow checker to analyze lifetimes using dataflow analysis instead of syntax trees. It significantly reduces compiler complexity and improves diagnostic precision.
