Rust Programming Tutorial #30 - Reading User Input

One of the most important things in a program is to read user input and in this video I show you how you can do this in Rust.

It is done through the stdin struct/stream and in this example we use the read_line method to feed user input from the console into a mutable String.

This is probably the most complicated way to take in input from a non esoteric language

These tutorials are incredibly helpful. I've done tons of programming before, but Rust confused me a great deal, and you've helped me greatly!

I did a tweak in order to check if the user hasn't input anything:
match io::stdin()
.read_line(&mut input) {
Ok(_) => {

if input == "\n" || input.trim().is_empty(){
println!("You didn't say anything.");
} else {
println!("Success! You said: {}", input.to_uppercase());
}
},
Err(e) => {
println!("Oops! Something went wrong: {}", e);
}
}
}

Hi,
What if i want no input from user, but i want the console will be stay there and when the user presses an "Enter" key, program can exit. In basic languages, they use "Sleep". In .net, they use Console.WriteLine() with no arguments. What is the rust equivalent ?

What code editor are you using? Is it vscode? It looks so different. Is it a theme?

@dcode Why in RUST, If you have to take integer input from user, you will take value as string, then convert into integer.
