This eliminates all compatibility problems: you can have as many programs as you want on your computer, each one compiled with a different version of a given library. And the point of the crates.io repository is to ensure that all versions of all libraries will forever be available, to ensure that a Rust program that depends on a specific version of a library will remain compilable. > > This is also something a typical package installation will not let me > control: they will just upgrade the other programs as well, whether I > want that or not. > This is a separate question, and I don't know which package manager you have in mind, but at least with Debian's package manager what you describe doesn't happen. You can always review what will be upgraded.
