Is it recommended to use a Rust virtual environment when installing programs with cargo? (feddit.it)

In python, when you install stuff with pip, it is recommended to use a venv, to avoid breaking dependencies for a program when uninstalling another one, or when two programs need two different versions of the same dependence.

I was wondering if with Rust is the same, or if Cargo manages it all on its own (kind of like apt does), and I shouldn't care about it.

Also since I know Linux kernel is using some Rust, isn't there a risk of breaking my system if I uninstall a program that need some deps that the system itsel needs?

You don't need to worry about that in rust. Cargo is built from the ground up to understand package versions and downloads/builds the right versions for each project. The global package caches understand versions and can cache multiple versions of each package. Where as python just uses one or more global stores of packages shared by all projects. venv is basically there to isolated these package stores along with the version of python which can have breaking changes between different releases (this is something rust avoids at all costs so you can upgrade it without worrying as much as with python).
