cargo-run-script is a Cargo subcommand which allows you to define scripts for common project related tasks within your 'Cargo.toml'. If you are familiar with node, cargo-run-script brings the npm run functionality to the Rust and Cargo ecosystem.

cargo-run-script requires Rust in order to build/install. If you need to install Rust, follow these instructions. Once you have Rust installed, cargo-run-script can be installed by running the command below:

cargo install cargo-run-script

Scripts are defined by adding a [package.metadata.scripts] section to the Cargo.toml file of your project, as shown below.

[package.metadata.scripts]
hello = "echo Hello"
goodbye = "echo Goodbye"

A more complete example can be seen by reviewing the Cargo.toml for this project.

From the root of your project directory (at the same level as the Cargo.toml), you can run your scripts as shown below.

# to run a script called "hello"
cargo run-script hello

The output of this would be

Running script 'hello': 'echo Hello'
Hello
Finished, status of exit code: 0
