Rust, the language

• A bit more than 10 years old (2010)
• Memory safe without gcing, optional ref counting
• Ownership, lifetimes, traits, functional paradigms
• Variables are immutable by default and can be shadowed
• Performance of idiomatic Rust is comparable to the performance of idiomatic C++
• A well designed language and ecosystem

Strengths and Weaknesses¹

Things Rust does measurably really well

• Compiled code about same performance as C / C++, and excellent memory and energy efficiency.
• Can avoid 70% of all safety issues present in C / C++, and most memory issues.
• Strong type system prevents data races, brings 'fearless concurrency' (amongst others).
• Seamless C interop, and dozens of supported platforms (based on LLVM).³
• "Most loved language" for 6 years in a row.
• Modern tooling: cargo (builds just work), clippy (450+ code quality lints), rustup (easy toolchain mgmt).

Strengths and Weaknesses¹

Points you might run into

• Steep learning curve⁴ compiler enforcing (esp. memory) rules that would be "best practices" elsewhere.
• Missing Rust-native libs in some domains, target platforms (esp. embedded), IDE features.⁴
• Longer compile times than "similar" code in other languages.⁴⁵
• No formal language specification, can prevent legal use in some domains (aviation, medical, …).⁶
• Careless (use of unsafe in) libraries can secretly break safety guarantees.
