What is new in Rust for 2019
summary
Rust 2018 features and tooling are shown with runnable examples: install via cargo, start projects with cargo new (now defaulting to binaries), run cargo run, and use the official rust language server with VS Code. The demo parses a -C=5 argument, uses parse with explicit types, demonstrates the question mark operator to propagate Result errors, shows index access causing a panic and backtrace, then fixes it by using get (Option) and converting to Result. Compiler version 1.32 is recommended.
