Each upgrade should be painless,īut should also bring you new features, fewer bugs, and faster compile times. you should never have to fear upgrading to a new version of stable Rust. The Rust project strives for stability without stagnation. The Rust compiler itself is a living piece of software: it continuously evolves and improves with the daily contributions of hundreds of volunteers.
Targets are split into tiers, from "guaranteed-to-work" Tier 1 to "best-effort" Tier 3.Īn exhaustive and up-to-date list can be found here. The Rust project strives to support a broad range of compilation targets with various level of guarantees. 64-bit Linux or 64-bit OSX) you want to produce a running executable for. Therefore you need a different backend of the Rust compiler for each compilation target, i.e. The main purpose of the Rust compiler is to convert Rust code into machine code - a set of instructions that your CPU and operating system can understand and execute. Rustup is more than a Rust installer - its main value proposition is toolchain management.Ī toolchain is the combination of a compilation target and a release channel. Instructions on how to install rustup itself can be found at. There are various ways to install Rust on your system, but we are going to focus on the recommended path: via rustup. Some of them are officially supported by the Rust organisation, others are built and maintained by the community. We are now going to take a brief tour of a set of tools and utilities that are going to be useful in our journey. The Rust community has put tooling at the forefront since its early days: it shows. Tooling should therefore be treated as a first-class concern both when designing and teaching the language itself. It often has a disproportionate impact on the uptake (or the demise) of the technology itself. There is more to a programming language than the language itself: tooling is a key element of the experience of using the language.
