*** 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

* Diesel

** What is an ORM?

** What is diesel capable of?

* Lets code something

* Conclusion

** What did we do?

** What did you hopefully learn!

** Two small projects

*** [[https://git.onders.org/finga/ldap0r][ldap0r]]
    - LDAP password reset tool
    - ($\sim$ 300 SloC)
    - First release
    - Tests

*** [[https://git.onders.org/finga/filerly][filerly]]
    - File sharing a la NextCloud
    - Not ready yet, work in progress...
