Rust intro for Java Developers
summary
Quick Rust primer for Java devs focusing on concrete differences and real tradeoffs: Rust enforces ownership, borrowing and lifetimes to provide memory safety without a GC, preventing segfaults and iterator invalidation; mutable state is explicit and references follow a single-writer/many-readers model. Structs + impl and traits replace Java classes/interfaces, generics are terser, and Cargo manages packages. Interop with C/C++ requires marking blocks unsafe and the recommendation is to wrap unsafe C calls in safe APIs. Performance varies (Mandelbrot >2× faster in one benchmark).
