rust - rustup 安装到哪里？

Question

我知道 rustup 将 rustc 和 cargo 二进制文件安装到 ~/.cargo/bin，但是它将 rustup 可执行文件安装到哪里？据我所知，这在任何文档中都没有解释，运行安装程序也不会告诉你。如果可能的话，我想避免将它安装到我的主目录以外的任何地方。如果有区别，我会使用 macOS。

默认，rustup 也会安装到您的主目录:

$ which rustup
/Users/shep/.cargo/bin/rustup

documentation states :

rustup installs rustc, cargo, rustup and other standard tools to Cargo's bin directory. On Unix it is located at $HOME/.cargo/bin and on Windows at %USERPROFILE%\.cargo\bin. This is the same directory that cargo install will install Rust programs and Cargo plugins.

它goes on to describe how to change the defaults :

rustup allows you to customise your installation by setting the environment variables CARGO_HOME and RUSTUP_HOME before running the rustup-init executable. As mentioned in the Environment Variables section, RUSTUP_HOME sets the root rustup folder, which is used for storing installed toolchains and configuration options. CARGO_HOME contains cache files used by cargo.
