Einführung in Rust

Rust ist eine moderne Programmiersprache, die Performance und Sicherheit verbindet. Sie ist systemnah und bietet leistungsstarke Abstraktionen, die stark an dynamische Sprachen wie Ruby oder Python erinnern. Rust bietet Speichersicherheit ohne Garbage Collector und macht die Low-Level-Programmierung einfacher und sicherer. Matthias wird einen einführenden Vortrag über Rust halten und in diesem Rahmen auch einige der schönsten Features vorstellen. Außerdem wird er auf Einsatzmöglichkeiten für WebAssembly, Cloud Computing und mehr eingehen.

3. What Is Rust Doing Behind the Curtains?
7. Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. It aims to bring modern language design and an advanced type system to systems programming. Rust does not use a garbage collector, using advanced static analysis to provide deterministic drops instead.
8. Empowering everyone
 to build reliable and efficient software.

16. Do What You Can't
18. Rust Facts • Programming language • Funded by Mozilla • First version: 2010 • Version 1.0: May 2015 • Current stable version: 1.40
19. Rust Facts • Memory safety • No undefined behavior • Fearless concurrency • High-level language concepts • Strong compiler checks • Easily embeddable into existing
 projects

43. ... but there's more! • How to differentiate between end of file and error? • Parallel execution for multiple files? • What about very long lines? • Buffers for performance • Timeouts for slow reads? • SIMD?
52. • Handles missing files • Handles read errors • Handles large files • UTF-8 support • Fast buffered reading • No memory leaks
