Managing the Rust installation with rustup.rs

To test whether the installation of the Rust toolchain with rustup was successful, the rustc command is available to run in Terminal (or PowerShell on Windows):

$ rustc --version
rustc 1.33.0 (2aa4c46cf 2019-02-28)

Note that you will have a later version when you are running this. It doesn't matter if you stick to the 2018 edition for your code.

Rust requires a native linker to be available on your system. On Linux or Unix systems (such as macOS), Rust calls cc for linking, whereas on Windows, the linker of choice is Microsoft Visual Studio's linker, which depends on having Microsoft Visual C++ Build Tools installed. While it's possible to use an open source toolchain on Windows as well, this exercise is left for more advanced users.

Even with the 2018 edition, some useful features are still only available on nightly. To install the nightly edition of rustc, perform these steps:

Run rustup install nightly (use nightly-msvc on Windows if you are not using the GNU toolchain) in a Terminal or PowerShell window.
After the command finishes, the default toolchain (used in cargo) can be switched using rustup default nightly.
