Despite being newer than Python, Rust has rapidly become a favorite among developers.

Rust finds applications in various domains, including system development, web applications, embedded systems, blockchain, and game engines. Over 84% of Developers using Rust, love it and want to keep working with it!

Advantages of Rust

Rust is known for its high performance. Below are other benefits of using Rust.

• Performance-Oriented Design: Rust prioritizes performance, offering faster execution and efficient memory usage compared to other languages. It avoids runtime overhead and eliminates the need for garbage collection.

• Strict Memory Safety: Rust ensures strict and safe memory management, enforcing secure coding practices that enhance stability and security in software development.

• Control Over Low-Level Resources: Developers using Rust gain direct and safe control over low-level resources, akin to the capabilities found in languages like C/C++.

Disadvantages of Rust

Rust has the following limitations.

• Slower Compilation Time: Rust’s compilation process can be slower compared to other languages because it compiles entire packages or crates at once, leading to longer wait times.

• Steep Learning Curve: Learning Rust may take more time compared to languages like Python. Familiarity with at least one programming language is recommended to effectively use Rust, making it less beginner-friendly.

• Limited Support for Monkey Patching: Rust does not offer extensive support for monkey patching, a technique for modifying or extending code at runtime, which can limit flexibility in certain programming paradigms.

• Larger Binary Files: Rust’s focus on performance and safety can result in larger binary files compared to languages that prioritize smaller executable sizes.

Key Features of Rust

Rust combines the strengths of C++ with additional features. Its main advantages are memory safety, thread safety, cross-platform support, and zero-cost abstractions.

• Memory Safety: Unlike C++, Rust avoids common memory issues through its ownership model and type system. This allows programs to detect and prevent bugs at compile time without needing a garbage collector.

• Thread Safety: Rust ensures thread safety by managing data ownership. Only one thread can write to a variable at a time, preventing race conditions where multiple threads access the same memory simultaneously.

• Zero-Cost Abstractions: Rust supports abstractions that don’t impact performance at runtime. This means using abstractions doesn’t add overhead, ensuring efficient code execution even with complex features.

• Cross-Platform Support: Rust enables development across different platforms like Windows, Linux, and macOS. Its cargo build tool simplifies deploying code to multiple platforms with minimal configuration.

Rust vs Python: Head-to-Head Comparison

1. Ease of Use/Learning

Python’s simplicity and extensive libraries make it globally popular and easy to learn. It’s recommended for beginners over Rust due to its straightforward syntax.

Python’s user-friendly development and broad application in diverse industries highlight its accessibility.

Researchers find Python straightforward, requiring fewer lines of code than Rust for similar tasks, making it the preferred choice for ease of learning and usability.

2. Performance

Rust excels in performance compared to Python. It’s built for high-performance applications, known for its speed and efficient memory management without an interpreter.

In contrast, Python’s performance is hindered by its interpreter and inefficient memory management with runtime garbage collection.

This makes Python less suitable for performance-intensive applications.

3. Garbage collection

Rust does not use runtime garbage collection, unlike Python. This means Rust does not spend time checking for unused memory during program execution, which can slow down performance.

In contrast, Python’s runtime garbage collection can contribute to slower program execution compared to Rust.

4. Memory Management

Python uses a garbage collector that continuously scans for unused variables in code and frees up memory accordingly.

In contrast, Rust utilizes an ownership model to manage memory, which checks for ownership rule violations during compilation.

Rust distinguishes between stacks (for scalar values) and heaps (for non-scalar values) to store data. This approach allows Rust to manage memory more efficiently than Python’s runtime garbage collector.

5. Error handling

Python handles errors by throwing exceptions at runtime without offering suggestions for fixes during compilation. This method lacks opportunities for improvement before runtime.

On the other hand, Rust identifies errors during compilation and suggests possible solutions without halting the program.

This approach makes error handling in Rust more straightforward and facilitates the creation of high-quality programs by catching issues early in the development process.

6. Security

Rust emphasizes security by focusing on memory safety through its Secure Rust Guidelines. It detects all memory issues during compilation, preventing unauthorized access to variables.

Additionally, the Rust team actively addresses security vulnerabilities in the Rust ecosystem, regularly issuing patches that developers can track through the Rust security announcements mailing list.
