chez Mozilla en 2006. +- Financé par Mozilla dès 2010. +- Rendu public la première fois en 2012 (version 0.4). +- Orientation vers la programmation système. +- Première version stable (1.0) en 2015. +- La très grande majorité des fonctionnalités du langages ont été retirées. +- Stabilisation de fonctionnalités tous les 6 semaines. +- Version stable actuelle 1.31. <!-- TODO UPDATE --> + +# Projets basés sur Rust + +- Firefox: + * Servo (moteur parallèle de navigateur en collaboration avec Samsung) + * Quantum (Moteur du navigateur de Firefox) +- Gnome (en remplacement du C). +- Dropbox. +- Npm. +- Cargo. +- Tor (en phase de tests). +- Redox (microkernel). +- <https://www.rust-lang.org/en-US/friends.html> + +# Concepts de base + +## Généralités + +- Des garanties de sûreté + - Pas de seg-faults. + - Pas d'accès concurrents. + - Un système de type expressif. + +- Sans coût de performance + - Pas de garbage collector. + - Pas d'overhead à l'exécution. + +- **Un langage "système" dans lequel on peut avoir confiance.** +<!-- Productivité: efficacité et maintenance "simple". --> + +# Sûreté mémoire + +## Un peu de C++ + +```{.cpp} +{ + vector<string> v; + ... + auto &elem = v[0]; + ... +} +``` + +## + +- Fortement typé. +- Pas d'accès mémoire illégal. +- La désallocation est automatique. +- Les fuites de mémoires sont TRÈS difficiles à faire. + +# Concurrence + +- *Concurrency without fear*. +- Le système de type empêche un accès concurrent à des données. +- La synchronisation des données doit être explicitement faite. +- Détection si l'accès asynchrone est sûr à la compilation. +- Protection contre les accès concurrents. + +## Rapidité + +- Abstractions à coût nul (langage moderne **ET** efficace). +- Les conditions de sécurité sont gérées *à la compilation* (pas de coût à l'exécution). +- Le compilateur est basé sur la LLVM. +- On paie pour ce qu'on utilise seulement. + +## On peut contourner les règles + +- Le compilateur a des règles très strictes... +- ... mais il est possible de contourner les règles. +- Syntaxe spéciale pour autoriser les comportement potentiellement dangereux (`unsafe`{.lang-rust}). +- Un guide pour bien vivre dangereusement <https://doc.rust-lang.org/nomicon/>. +
