Since this book is about learning Rust, primarily in a microservices
environment, this chapter focuses on installing Rust and describing the tools
available to the developer.

The easiest way to install Rust is to install the [Rustup](https://rustup.rs/)
tool. It is one of those blind-trust-in-the-safety-of-the-toolchain things. For
Linux and Mac users, the command is a shell script that installs to a user's
local account:

``` sh
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```

Once installed, you can install Rust itself:

``` sh
$ rustup install toolchain stable
```

You should now have Rust compiler and the Rust build and packaging tool, known
as Cargo:

``` sh
$ rustc --version
rustc 1.68.0 (2c8cc3432 2023-03-06)
$ cargo --version
cargo 1.68.0 (115f34552 2023-02-26)
```

I also installed the following tools:

``` sh
$ rustup component add clippy rust-src rust-docs
$ cargo install rustfmt rust-analyzer
```

- clippy: A powerful linter that provides useful advice above and beyond the
  compiler's basic error checking.
- rustfmt: A formatting tool that provides a common format for most developers
- rust-analyzer: For your IDE, rust-analyzer provides the LSP (Language Server
  Protocol) for Rust, giving you code completion, on-the-fly error definition,
  and other luxuries.
