*** 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 Weaknesses[fn:2]
*** Things Rust does measurably really well
    - Compiled code [[https://benchmarksgame-team.pages.debian.net/benchmarksgame/which-programs-are-fastest.html][about same performance as C / C++]], and excellent
      [[https://dl.acm.org/doi/10.1145/3136014.3136031][memory and energy efficiency]].
    - Can [[https://www.chromium.org/Home/chromium-security/memory-safety][avoid 70% of all safety issues]] present in C / C++, and most
      memory issues.
    - Strong type system prevents [[https://doc.rust-lang.org/nomicon/races.html][data races]], brings [[https://blog.rust-lang.org/2015/04/10/Fearless-Concurrency.html]['fearless
      concurrency']] (amongst others).
    - Seamless C interop, and [[https://doc.rust-lang.org/rustc/platform-support.html][dozens of supported platforms]] (based on
      LLVM).[fn:3]
    - [[https://insights.stackoverflow.com/survey/2021#technology-most-loved-dreaded-and-wanted]["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 Weaknesses[fn:2]
*** Points you might run into
    - Steep learning curve[fn:4] compiler enforcing (esp. memory)
      rules that would be "best practices" elsewhere.
    - Missing Rust-native libs in some domains, target platforms
      (esp. embedded), IDE features.[fn:4]
    - Longer compile times than "similar" code in other
      languages.[fn:4][fn:5]
    - No formal language specification, can prevent legal use in some
      domains (aviation, medical, ...).[fn:6]
    - Careless (use of ~unsafe~ in) libraries can secretly break
      safety guarantees.
