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.
