How to read a string from keyboard on the same line with output? [duplicate]

Question

I'm reading a string like this:

print!("Input string: "); 

let string: String = String::new();
std::io::stdin().read_line(&mut string);

When I launch the program I see:

(write a string here)
Input string:

But I need:

Input string: (write a string here)

How to implement this?

Answer 1

Add a call to stdout().flush() to force the buffer to output before read_line is called:

fn main() {
   print!("Input string: "); 
   std::io::stdout().flush();
   let mut string: String = String::new();
   std::io::stdin().read_line(&mut string);
}
