(It seemed to stall at page 83 of 89 pages installed - 35% of the status bar - and then suddenly shot up to 96%.)Īnd when it was finished, a reboot was required.īut one reboot later, and I was running rustup… Getting Started With Cargo The Visual Studio Installer alone was 67 megabytes, and Visual Studio Build Tools 2019 required 1.15GB more on my laptop - and took nearly 12 minutes to install. You can select the installation of build tools from Visual Studio’s workspace screen - although downloading them takes several long minutes… In my case, I also needed to install the Microsoft C++ Build Tools - but Rustup-Init.exe told me I could get them by installing Microsoft’s Visual Studio IDE and then making sure that it also installed the C++ build tools - and even gave me the appropriate URL. Rustup checks for the necessary prerequisites, and lets you know if anything’s missing. You just download and run a file named Rustup-Init.exeīut of course, it wasn’t that easy… Installation and a Detour So it seems deceptively simple to install Rust on a Windows system. But another neat thing about rustup is it makes it easy for you to manually switch between those three versions of the Rust compiler - the stable, beta, and nightly versions.Īnd if you want to make sure your rustup tool is up to date, you type… Rustup’s official documentation calls this “the essence of rustup”. For example, rustup comes in handy when it’s time to update to a newer version of Rust. ![]() Rustup is officially described as a “toolchain multiplexer” that installs several of the important Rust tools.

One choice lets you compile your code without running it - with or without testing it for errors - or to convert it to Assembly or to WebAssembly.Īnd other choices let you convert your code to MIR (Rust’s “Mid-level Intermediate Representation”) or to LLVM IR (the intermediate representation for the Low-Level Virtual Machine that Rust uses as its backend). There’s also a down-pointing arrow that brings up a menu for choosing which version of Rust to run - the current stable version, or the “beta” version (a more-recent version that gets updated every six weeks, according to the official Rust blog).Īnd in addition, every 24 hours the last successful new build becomes the new “nightly” build, to “give early adopters access to unfinished features as we work on them.” This is also available through the same menu (via that down-pointing arrow).īut even the playground’s “Run” option has several choices. The three dots on the far right pull up a menu that lets you select which Rust to run - either the earlier 2015 edition or the 2018 edition - and whether or not you want to enable a debugging backtrace when it executes to give you even more visibility into how the program runs. That page features a lot of bells and whistles. It starts you off with a pre-written “Hello world!” program, and dares you to take it from there. ![]() There’s a browser-based online “Rust Playground” where you can mess around with the language yourself. The first thing I learned is that the Rust ecosystem is surprisingly robust - and that it’s possible to run Rust code without even installing anything. ![]()
