Can You Use Rust as a Scripting Language?

When it comes to scripting languages, Rust may not be the first language that comes to mind. Rust is known for its focus on performance, safety, and low-level system programming. However, with the right tools and libraries, Rust can indeed be used as a scripting language.

The Benefits of Using Rust as a Scripting Language

Rust offers several advantages when it comes to scripting:

  • Performance: Rust is designed for high-performance applications. Its strict compile-time checks and zero-cost abstractions enable developers to write scripts that execute quickly.
  • Safety: One of the key features of Rust is its emphasis on memory safety.

    This makes it an excellent choice for writing secure scripts that are less prone to common programming errors like null pointer dereferences or buffer overflows.

  • Concurrency: Rust’s ownership system allows for safe and efficient concurrent programming. This feature can be particularly useful in scripting scenarios where parallel execution is required.

Using External Libraries

Rust’s standard library provides a solid foundation for writing scripts. However, to make the most out of Rust as a scripting language, you’ll likely need to rely on external libraries.

Rustdoc, the official documentation generator for Rust, provides extensive documentation on available libraries. Some popular libraries for scripting include:

  • Clap: A powerful command-line argument parsing library that makes it easy to handle command-line input in your scripts.
  • Serde: A serialization/deserialization library that allows you to easily convert data structures to and from different formats such as JSON or TOML.
  • Reqwest: A convenient HTTP client library that enables your scripts to interact with web APIs.

Creating a Script in Rust

To demonstrate how Rust can be used as a scripting language, let’s create a simple script that fetches weather information from an API and prints it to the console using the Reqwest library:

use reqwest;

fn main() -> Result<(), Box> {
    let response = reqwest::blocking::get("")? .text()? 

    println! ("Weather information: {}", response);

Compiling and Running the Script

To compile and run the script, follow these steps:

  1. Install Rust: If you haven’t already, install Rust by following the instructions on the official website (
  2. Create a new project: Open your terminal or command prompt, navigate to your desired directory, and run the command cargo new script-name. Replace “script-name” with the desired name of your script.
  3. Edit the Cargo.toml file: Open the generated Cargo.toml file in a text editor and add the following line under [dependencies]:
    reqwest = "0.11"
  4. Edit src/ Replace the content of src/ with the code provided above.
  5. Build and run the script: In your terminal or command prompt, navigate to the project directory and run the command cargo run.


While Rust may not be the most traditional choice for a scripting language, its performance, safety, and concurrency features make it a viable option. By leveraging external libraries, you can extend Rust’s capabilities and create powerful scripts. With its growing ecosystem and community support, Rust continues to prove its versatility as a language.

So, if you’re looking for a scripting language that offers both speed and safety, give Rust a try!
