multirust

If you want to play around with the code in this post that requires nightly, multirust makes it much more pleasant to use nightly and / or stable rust. https://github.com/brson/multirust

They are tools for managing multiple installed versions of a programming language. When developing software, we often specify dependencies using version numbers, which indicate the version of the language or library that should be used when running the software. Running the software with the specified language runtime or library version ensures that the expected features of that library or language runtime are available and also helps avoid unexpected issues related to differences in the environments, including different developer's local systems as well as remote server environments. In the case of a programming language runtime, if you have one project that's configured to use version 2.2.4 of a language and another that's configured to use version 2.1.0, these tools provide an easy way to install and switch between the two versions. Th

Run rustup.sh again, and it will Just Work. (If not, that's a bug.) If you want to have multiple versions installed at the same time, https://github.com/brson/multirust is super cool. Generally speaking, installation is something we're working on: working with Linux package maintainers, rolling rustup and multirust together and making them work well cross-platform, etc.

My impression is that things are settling down now, but I've encountered quite a few rust code bases that required "latest rust" (latest > 1.0) - and even "nightly". Not to say that rust-the-language hasn't stabilized, but I think the point about D being (way) more mature still stands? (Note, it's a good thing that people are writing code to test/work with/exercise latest rust/nightly etc -- but just because I can be fairly sure code I write today will compile tomorrow (which is good!) -- that doesn't mean "all of rust land" is stable). Please don't take this of critique of all the hard work going into rust -- the only way this wouldn't be a thing was if rust core was a dead project. [ed: To add to that - it might well be that all of the projects I've seen lately where I've had to wake up multirust[1] and do a little dance before my beaut

Won't nightly be the new stable in about ~15 weeks? That is pretty damn amazing. Using multirust [1] makes it easy to track (cargo,rust) for stable, beta and nightly on a per directory basis, super handy. [1] https://github.com/brson/multirust
