Featured Assignments
Rust-based Web Scraper
Web Scraping with RustClient Requirements
The student needed to develop a web scraper using Rust that could extract structured data from a given website, such as product details, including name, price, and availability. The student wanted to implement Rust's concurrency model to speed up the scraping process and store the data in a CSV file.
Challenges Faced
We ensured the scraper could handle a high number of requests concurrently without overwhelming the server. However, the student faced complications handling dynamic content (JavaScript-loaded data) and efficiently parsing the HTML without excessive memory consumption.
Our Solution
We implemented the scraper using the reqwest crate for HTTP requests and select for parsing the HTML. Rust’s asynchronous features (via tokio) were used to make multiple requests concurrently. The extracted data was then written to a CSV file using the csv crate, and error handling was integrated to manage failed requests.
Results Achieved
The scraper successfully fetched data from the website and stored it in a CSV format. The use of asynchronous tasks allowed the scraper to run efficiently, even for websites with multiple pages, and data was extracted with minimal delays.
Client Review
I had a great experience working on this assignment! The web scraper was efficient and ran in parallel, thanks to Rust’s concurrency features. The result exceeded my expectations, and I learned a lot about Rust's async programming. I’m pleased with the final product!
Rust-based Command Line Tool for Data Analysis
Data Processing with RustClient Requirements
The student needed to create a command-line tool in Rust to process a large dataset (CSV format). The tool should allow the user to perform operations like filtering, sorting, and aggregating data based on certain criteria (e.g., sum, average, or count). The tool should be highly performant and handle large files efficiently.
Challenges Faced
We ensured that the program could handle large datasets without consuming too much memory, but the student faced challenges managing memory efficiently while performing the necessary data transformations. Additionally, ensuring that the program remained responsive when processing large files was difficult.
Our Solution
We used Rust’s csv crate to parse the CSV data efficiently and implemented custom functions for filtering, sorting, and aggregating data. Rust’s ownership system helped to manage memory effectively, ensuring no unnecessary allocations. The use of iterators and Rust's powerful pattern matching made the tool both efficient and concise.
Results Achieved
The tool performed well, even with large datasets, and the user could easily filter, sort, and aggregate data. The command-line interface was intuitive, and the program ran efficiently without excessive memory usage.
Client Review
This assignment was both challenging and rewarding. The tool was fast and worked seamlessly with large datasets. I appreciated how Rust's memory safety features helped me avoid performance pitfalls. Overall, it was a very positive experience, and the result was exactly what I needed.
Rust-based Real-Time Chat Application
Real-Time Applications with RustClient Requirements
The student needed to develop a real-time chat application in Rust using the tokio framework for asynchronous operations. The app should support multiple users, allowing them to send and receive messages in real time, and include features like user authentication and private chats.
Challenges Faced
We ensured the application could handle multiple concurrent users, but the student faced complications with managing WebSocket connections efficiently and securely. Ensuring message delivery in real time without latency was also a key challenge.
Our Solution
We used the tokio crate to handle asynchronous tasks and warp for building the WebSocket server. Authentication was managed using JWT tokens, and a message queue ensured that messages were sent and received in real time. We also added robust error handling and logging to manage connection failures.
Results Achieved
The chat application allowed multiple users to send and receive messages in real time, with private messaging and secure authentication. It was scalable and could handle multiple concurrent users without noticeable latency.
Client Review
This real-time chat app project was a fantastic learning experience! Rust’s async features were perfect for building a scalable chat system. The implementation of WebSocket communication and authentication went smoothly, and I was pleased with the final result. I feel much more confident in my Rust skills now.
Rust-based File Compression Tool
Building Efficient Tools with RustClient Requirements
The student wanted to develop a file compression tool using Rust that could compress and decompress files in a popular format (e.g., .zip). The tool should handle large files efficiently and provide basic options such as password protection and multi-threaded compression.
Challenges Faced
We ensured the compression tool was fast, but the student faced challenges managing large files without running into memory issues. Implementing password protection and ensuring multi-threaded performance without conflicts was also a complex task.
Our Solution
We used Rust’s flate2 crate for compression and decompression and implemented multi-threading using the rayon crate to speed up the process. Password protection was added by integrating an encryption library to handle encryption and decryption of the files. Efficient memory management techniques were used to minimize memory usage during compression.
Results Achieved
The file compression tool worked efficiently with large files, offering options for compression, decompression, and password protection. Multi-threading made the tool faster, and the encryption feature ensured file security.
Client Review
Working on this file compression tool was a great challenge! I learned a lot about memory management and multi-threading in Rust. The tool handled large files effectively and was faster than I expected. The addition of password protection was a great feature, and I’m very happy with the results!
