How to prototype in Rust?

• use simple types: String, Vec, Box, Rc and Arc<Mutex> to avoid ownership and lifetime issues.
• make use of type inference
• use .unwrap(), and quick context with bail!() und with_context of the crate anyhow
• run the code (and tests) automatically with bacon
• have a look to cargo-script
• Use println! and dbg! for debugging: dbg! has advantages such as printing file name and line number, outputs the expression adn less syntax-heavy. dbg!(x)
• Design through types
• rely on the todo! macro
• rely on the unreachable! for assumptions of dead code branches: it documents assumptions
• rely on assert! for invariants: it documents assumptions
• avoid generics and lifetimes: use concrete types and owned types
• keep a flat hierarchy (of files), then only starts playing with mod around. All in the same file.
• start small
