This video explains where Rust build time goes, how each optimization works, which features require Nightly Rust, and how combining them reduced clean builds and rebuilds by nearly 50% in the demonstrated project. Chapters 0:00 Intro 0:42 How Cargo Build Works 1:13 Optimization 1: Reduce Debug Information 2:06 Optimization 2: Parallel Type Checking 3:06 Optimization 3: Cranelift Code Generation 4:00 Results With All Three Optimizations
