**Rust** (ラスト) は、性能、メモリ安全性、安全な並行性を目指して設計されたマルチパラダイムのプログラミング言語である。C 言語、C++ に代わるシステムプログラミング言語を目指しており、構文的にはC++に似ているが、「ボローチェッカー」(borrow checker) で参照の有効性を検証することによってメモリ安全性を保証できる。Rust はガベージコレクションなしでのメモリ安全性を達成しており、必要な場面で参照カウントを使うこともできる。\\

<b class=BOLD>info:</b> downloading installer

<b class=BOLD>Welcome to Rust!</b>

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/tomoyan/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

  /home/tomoyan/.cargo

This can be modified with the CARGO_HOME environment variable.

The <b class=BOLD>cargo</b>, <b class=BOLD>rustc</b>, <b class=BOLD>rustup</b> and other commands will be added to
Cargo's bin directory, located at:

This path will then be added to your <b class=BOLD>PATH</b> environment variable by
modifying the profile files located at:

  /home/tomoyan/.profile
  /home/tomoyan/.bash_profile
  /home/tomoyan/.bashrc

You can uninstall at any time with <b class=BOLD>rustup self uninstall</b> and
these changes will be reverted.

これにより、Rust プログラミング言語の公式コンパイラとそのパッケージマネージャーである Cargo がダウンロードおよびインストールされます。

Rustupメタデータとツールチェーンは、次の場所にあるRustupホームディレクトリにインストールされます。

これは、RUSTUP_HOME 環境変数を使用して変更できます。

次の場所にある Cargo ホームディレクトリ：

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, run:
source "$HOME/.cargo/env"

</WRAP>

<WRAP mincode>
<code bash $HOME/.cargo/env>
#!/bin/sh
# rustup shell setup

        ;;
    *)
        # Prepending path in case a system-installed rustc needs to be overridden
        export PATH="$HOME/.cargo/bin:$PATH"

<b class=BOLD>Welcome to Rust!</b>

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:

  /data/data/com.termux/files/home/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

  /data/data/com.termux/files/home/.cargo

This can be modified with the CARGO_HOME environment variable.

The <b class=BOLD>cargo</b>, <b class=BOLD>rustc</b>, <b class=BOLD>rustup</b> and other commands will be added to
Cargo's bin directory, located at:

  /data/data/com.termux/files/home/.cargo/bin

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

  /data/data/com.termux/files/home/.profile
  /data/data/com.termux/files/home/.bashrc

You can uninstall at any time with <b class=BOLD>rustup self uninstall</b> and
these changes will be reverted.

Current installation options:


   default host triple: <b class=BOLD>aarch64-linux-android</b>
     default toolchain: <b class=BOLD>stable (default)</b>
               profile: <b class=BOLD>default</b>
  modify PATH variable: <b class=BOLD>yes</b>

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

===== ツールチェイン (toolchain) =====

Rust のツールチェーン仕様は <html><pre><code>&lt;channel>[-&lt;date>][-&lt;host>]

&lt;channel>       = stable|beta|nightly|&lt;major.minor>|&lt;major.minor.patch>
&lt;date>          = YYYY-MM-DD
&lt;host>          = &lt;target-triple>
</code></pre></html>
例: stable-x86_64-unknown-linux-gnu\\
**channel:** //stable//\\
**date:** \\
**host:** //x86_64-unknown-linux-gnu (target-triple)//\\

esp32 マイコン用の <html><code>esp</code></html> ツールチェーンは [[rust:rust_on_esp_install#ツールチェーンのインストール|espup]] で追加する。\\

      <b>--help</b>                 Print help information.
  <b>-a</b>, <b>--all</b>                  write counts for all files, not just directories
      <b>--apparent-size</b>        print apparent sizes, rather than disk usage although the apparent size is
                             usually smaller, it may be larger due to holes in (&apos;sparse&apos;) files, internal
                             fragmentation, indirect blocks, and the like
  <b>-B</b>, <b>--block-size</b> &lt;SIZE&gt;    scale sizes by SIZE before printing them. E.g., &apos;-BM&apos; prints sizes in units of
                             1,048,576 bytes. See SIZE format below.
  <b>-b</b>, <b>--bytes</b>                equivalent to &apos;--apparent-size --block-size=1&apos;
  <b>-c</b>, <b>--total</b>                produce a grand total
  <b>-d</b>, <b>--max-depth</b> &lt;N&gt;        print the total for a directory (or file, with --all) only if it is N or fewer
                             levels below the command line argument;  --max-depth=0 is the same as --summarize
  <b>-h</b>, <b>--human-readable</b>       print sizes in human readable format (e.g., 1K 234M 2G)
      <b>--inodes</b>               list inode usage information instead of block usage like --block-size=1K
  <b>-k</b>                         like --block-size=1K
  <b>-l</b>, <b>--count-links</b>          count sizes many times if hard linked
  <b>-L</b>, <b>--dereference</b>          follow all symbolic links
  <b>-D</b>, <b>--dereference-args</b>     follow only symlinks that are listed on the command line [short aliases: H]
  <b>-P</b>, <b>--no-dereference</b>       don&apos;t follow any symbolic links (this is the default)
  <b>-m</b>                         like --block-size=1M
  <b>-0</b>, <b>--null</b>                 end each output line with 0 byte rather than newline
  <b>-S</b>, <b>--separate-dirs</b>        do not include size of subdirectories
  <b>-s</b>, <b>--summarize</b>            display only a total for each argument
      <b>--si</b>                   like -h, but use powers of 1000 not 1024
  <b>-x</b>, <b>--one-file-system</b>      skip directories on different file systems
  <b>-t</b>, <b>--threshold</b> &lt;SIZE&gt;     exclude entries smaller than SIZE if positive, or entries greater than SIZE if
                             negative
  <b>-v</b>, <b>--verbose</b>              verbose mode (option not present in GNU/Coreutils)
      <b>--exclude</b> &lt;PATTERN&gt;    exclude files that match PATTERN
  <b>-X</b>, <b>--exclude-from</b> &lt;FILE&gt;  exclude files that match any pattern in FILE
      <b>--files0-from</b> &lt;FILE&gt;   summarize device usage of the NUL-terminated file names specified in file F; if F
                             is -, then read names from standard input
      <b>--time</b>[=&lt;WORD&gt;...]     show time of the last modification of any file in the directory, or any of its
                             subdirectories. If WORD is given, show time as WORD instead of modification time:
                             atime, access, use, ctime, status, birth or creation [possible values: atime,
                             access, use, ctime, status, birth, creation]
      <b>--time-style</b> &lt;STYLE&gt;   show times using style STYLE: full-iso, long-iso, iso, +FORMAT FORMAT is
                             interpreted like &apos;date&apos;
  <b>-V</b>, <b>--version</b>              Print version

Display values are in units of the first available SIZE from --block-size,
and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.
Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).

SIZE is an integer and optional unit (example: 10M is 10*1024*1024).
Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB,... (powers
of 1000).

PATTERN allows some advanced exclusions. For example, the following syntaxes
are supported:
? will match only one character
* will match zero or more characters
{a,b} will match a or b

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.
