Rayon is a data parallelism library for the Rust programming language. Common reactions from programmers who start to use Rayon express how it seems magical: “I changed one line and my code now runs in parallel!” As one of Rayon’s authors, I am of course glad to see happy users, but I want to dispel some of the magic and give credit where it’s due—to Rust itself.

Several months ago, the LLVM project blog published an article, Closing the gap: cross-language LTO between Rust and C/C++. In it, they explained that link-time optimization can improve performance by optimizing throughout the whole program, such as inlining function calls between different objects. Since Rust and Clang both use LLVM for code generation, we can even achieve this benefit across different programming languages.
In Red Hat Developer Tools, we have the Rust and LLVM Toolsets, which can easily be used together for cross-language link-time optimization (LTO), so let’s try it out.

A few weeks ago, I had the pleasure of attending the second annual Rust All Hands meeting, hosted by Mozilla at their Berlin office. The attendees were a mix of volunteers and corporate employees covering the full range of Rust development, including the compiler, language, libraries, docs, tools, operations, and community. Although I’m sure there will be an official summary of the meeting (like last year’s), in this article, I’ll cover a few things I was directly involved in. First, I’ll look at a feature many developers have wanted for a long time…

One of the new software collections we’ve introduced this fall is for Rust, the programming language that aims for memory and thread safety without compromising performance. Dangling pointers and data races are caught at compile time, while still optimizing to fast native code without a language runtime!
In rust-toolset-7, we’re including everything you need to start programming in Rust on Red Hat Enterprise Linux 7, in the familiar format of software collections. In this release, we’re shipping Rust 1.20 and its matching Cargo 0.21 – both as Tech Preview. (NOTE: The “-7” in our toolset name is to sync with the other collections now being released, devtoolset-7, go-toolset-7, and llvm-toolset-7.)
