rust

Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).

To configure your current shell, you need to source
the corresponding env file under $HOME/.cargo.

This is usually done by running one of the following (note the leading DOT):
. "$HOME/.cargo/env"            # For sh/bash/zsh/ash/dash/pdksh
source "$HOME/.cargo/env.fish"  # For fish

update:

現在deb apt 里有 rust/cargo 了，只要

apt install rustc

就會install rustc.

apt install cargo

就會 install cargo 和 rustc.

rustc 就像是 gcc, cargo 就像是 make

update :

現在官方安裝方式是 rustup

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

然後就是

info: downloading installer

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:

  /home/charles/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

  /home/charles/.cargo

This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:

  /home/charles/.cargo/bin

This path will then be added to your PATH environment variable by
modifying the profile files located at:

  /home/charles/.profile
  /home/charles/.bashrc

You can uninstall at any time with rustup self uninstall and
these changes will be reverted.
