info: downloading installer
warn: It looks like you have an existing rustup settings file at:
warn: /root/.rustup/settings.toml
warn: Rustup will install the default toolchain as specified in the settings file,
warn: instead of the one inferred from the default host triple.
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:
/root/.rustup
This can be modified with the RUSTUP_HOME environment variable.
The Cargo home directory is located at:
/root/.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:
/root/.cargo/bin
This path will then be added to your PATH environment variable by
modifying the profile files located at:
/root/.profile
/root/.bashrc
You can uninstall at any time with rustup self uninstall and
these changes will be reverted.
Current installation options:
default host triple: x86_64-unknown-linux-gnu
default toolchain: stable (default)
profile: default
modify PATH variable: yes
1) Proceed with standard installation (default - just press enter)
2) Customize installation
3) Cancel installation

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 "$HOME/.cargo/env.fish" # For fish
source "~/.cargo/env.nu" # For nushell
source "$HOME/.cargo/env.tcsh" # For tcsh
. "$HOME/.cargo/env.ps1" # For pwsh
source "$HOME/.cargo/env.xsh" # For xonsh
