Einführung in Rust

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.

  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.
