*** Rust: the language
    - About 10 years old (2010)
    - Memory safe without gcing, optional ref counting
    - Ownership, lifetimes, traits
    - Variables are immutable by default and can be shadowed
    - Performance of idiomatic Rust is comparable to the performance
      of idiomatic cpp

** Where to get infos

*** Chat (Discord)
    - [[https://discord.gg/rust-lang][The Rust Programming Language]]
    - [[https://discord.com/invite/tcbkpyQ][The Rust Programming Language Community Server]]

*** Some links

    - [[https://cheats.rs][cheats.rs]]
    - [[https://cargo.io][cargo.io]]/[[https://lib.rs][lib.rs]]

** What are we going to use?

*** Definitely

   - [[https://diesel.rs][diesel]]
   - log

*** Maybe
   - anyhow
   - lettre
   - sha3

    $ rustup toolchain install nightly
    #+END_SRC

*** Install rustfmt
    #+BEGIN_SRC sh
    $ rustup component add rustfmt
    #+END_SRC

*** Install clippy (Linter and static code analysis)
    #+BEGIN_SRC sh
    $ rustup component add clippy
    #+END_SRC
