Rust

Rust 编程语言持续流行，并连续五年被开发人员们评为 Stack Overflow 的“最受喜爱”语言。我们当然也喜欢它。它是一种快速，安全且富有表现力的语言，随着它的生态系统发展，其实用性也不断提高。例如，Rust 开始用于数据科学和机器学习，并能显著提高性能。同时，用 Rust 编写的面向流的低延迟数据库 Materialize 也应运而生。

Rust 日益受到欢迎。曾经，Rust、C++ 和 Go 哪门语言更好的讨论火了一段时间，谁是赢家却尚未明确。近期，令人感到高兴的是，Rust 改善显著，添加并稳固了更多内置 API，包括上一期技术雷达中提到的高级异步支持。此外，Rust 还启发了新语言的设计。例如， Libra 区块链上的 Move 语言 借鉴了 Rust 的内存管理方式来管理资源，从而确保了数字资产永远不会被复制或隐式丢弃。

Since we last featured it on the Radar in January 2015, we've seen steadily increasing interest in Rust. Some of our clients are now using Rust, mostly in the context of infrastructure tooling but also in high-powered embedded devices. Interest was fuelled by a growing ecosystem as well as improvements to the language itself. The latter included straightforward performance improvements but also changes that make Rust more intuitive, for example the change to non-lexical scoping. Most of the significant changes are included in the Rust 2018 standard released last December.

Rust is a system programming language with modern affordances. It features a rich typing system, safe memory model and task-based concurrency. Compared to the Go language, Rust is more friendly to people who would like to write code in a functional style.
