Example
A lightweight collection of examples demonstrating essential Rust features,
without relying on external dependencies (except tokio).
Concepts Covered
- Arrays and Iteration
- Lifetimes and Borrowing
- Error Handling with
Result,?, and custom messages - Async Programming using
#[tokio::main] - File I/O with the standard library
- Unit and async testing
Key Functions
| Function | Description |
|---|---|
longest |
Returns the longest string in a slice without copying. |
read_and_parse |
Reads a file and parses its content into an integer. |
run_tasks |
Demonstrates spawning and awaiting async tasks. |
Testing
Includes both synchronous and asynchronous unit tests under a
#[cfg(test)] module.
Testing & Extending
Requirements
- Rust 1.76+ (for full language support)
- Tokio 1.37+ (for async runtime)
