> Perhaps not quite as safe, but at least that they deliver the important parts of that safety without the cost of the learning curve. Sorry to say this but a lot of unsafe code has been written in Java or C#, putting aside the NPEs and such. In Rust safety isn't only about eliminating SEGFAULTs and buffer overflows, but also preventing data races and most concurrency issues. It's common to add threading to cpu-bound code, without worrying about deadlocks or race conditions. Rust also allows some very high-level code. Some of my favorite options out there: - option (std): https://doc.rust-lang.org/std/option/index.html - serde: https://github.com/serde-rs/serde - docopt: https://github.com/docopt/docopt.rs Some more features: generics (traits!), immutability by default, type inference, first-class functions, operator overloading, conversi
