Rust: A Friendly Introduction
summary
Claim: Rust gives zero-cost abstractions and memory safety without paying a runtime GC tax by combining ownership and borrow checker rules, explicit pointer kinds (owned, managed, borrowed, raw) and LLVM-backed codegen. Examples include Servo prototype browser work and a NES emulator with real trait-based interfaces; microbenchmarks approach C speed. Tools shown: rustc, macros, unit test and benchmark harnesses; project has 100+ contributors and targets Linux, Mac, Windows and Android.
