Cargo run/debug configuration

Allow multiple instances

Enable this option if you want to allow multiple instances of the configuration to run simultaneously. Otherwise, re-running the configuration will terminate the active session.

Store as project file

Enable this option to save your configuration as a project file and share it with team members through VCS.

Command

Use the following pattern when specifying the command:

[command] [build options] [--] [program arguments]

The -- prefix followed by an extra space separates Cargo build options from input arguments.

Channel

Optionally, specify the preferred channel. It will only affect the current configuration.

Automatically add required features if possible

This option adds --features="feature_name" for all required-features listed in relevant Cargo.toml files. The option is enabled by default.

Use all features in tests

This option adds the --all-features flag if you are running a cargo test command. For other commands, this option is ignored.

Emulate terminal in output console

This option can be useful for crates like color-backtrace, which behave differently when a process is run under TTY (refer to the feature description). This option is not available on Windows.

Run with root privileges / Run with Administrator privileges

Enable this option to debug your application as root.

For more information, refer to Debug as root.

Environment variables

Optionally, specify environment variables (overriding or custom). Format them as key-value pairs separated with semicolons, for example:

HOME=/home/me.user;MY_APP_DATA=/home/me.user/appdata

Working directory

If needed, change the directory used by the running task.

Redirect input from

This option allows you to take program input from a file instead of the console.

Backtrace

This option sets the RUST_BACKTRACE environment variable, which prints the unwound stack trace into error messages and controls its length.

For more information, refer to Backtrace

Before launch

Here you can specify the steps to execute before launch. By default, the Build step is included, which means the IDE will rebuild your sources on every run.

Show this page

Enable this option to always show the run/debug configuration settings prior to actually starting it.

Activate tool window

Use this option to specify whether or not the Run/Debug tool window opens when you start the run/debug configuration.
