Building a Simple CLI To-Do App in Rust Using Cargo

Originally published on .

Once installed, create a new Rust project:

cargo new rust_todo

cd rust_todo

Now, open the main.rs file and start coding!

Code Breakdown

2. Handling User Input

The stdin().read_line(&mut variable).unwrap(); reads input from the user.

4. Viewing Tasks

We loop through the tasks vector and print each task.

6. Handling Invalid Input

We use match choice.trim().parse() to handle parsing errors gracefully.

Conclusion

This simple CRUD app demonstrates basic Rust concepts like structs, vectors, loops, and error handling. You can expand it by adding features such as persistent storage using files or a database.

Happy coding with Rust!
