info: downloading installer
Welcome to Rust!
This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.
It will add the cargo, rustc, rustup and other commands to
Cargo's bin directory, located at:
/Users/username/.cargo/bin
This can be modified with the CARGO_HOME environment variable.
Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:
/Users/username/.rustup
This can be modified with the RUSTUP_HOME environment variable.
This path will then be added to your PATH environment variable by
modifying the profile files located at:
/Users/username/.profile
/Users/username/.zprofile
/Users/username/.bash_profile
You can uninstall at any time with rustup self uninstall and
these changes will be reverted.
Current installation options:
default host triple: x86_64-apple-darwin
default toolchain: stable
profile: default
modify PATH variable: yes
1) Proceed with installation (default)

Rust is installed now. Great!
To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH
environment variable. Next time you log in this will be done
automatically.
To configure your current shell run source $HOME/.cargo/env
確認
バージョンを確認して、インストールされているか確認してみます。
$ rustc --version
zsh: command not found: rustc
パスが通ってなかったので、通します。
$ source $HOME/.cargo/env
インストールされていました。
$ rustc --version
rustc 1.38.0 (625451e37 2019-09-23)
今後
これから、 Rust の勉強をはじめていきます。
