Cargo

differences between debug and release builds

• faster compile for debug
• debug crashes on purpose on some errors to show the programmer
• optimizations for release
• cargo run builds and run the main program

Modes

• canonical mode or cooked
  • keyboard input is only sent on Enter
• raw mode enable_raw_mode().unwrap(); disable_raw_mode().unwrap();

Reading bytes

for b in io::stdin().bytes() {
    match b {
         Ok(b) => {
            let c = b as char;
            if c.is_control() {
                println!("Binary: {:08b} ASCII: {0:#03}\r", b);
            } else {
                println!("Binary: {:08b} ASCII: {0:#03} Char: {1:#?}\r", b, c);
            }
 
            if c == 'q' {
                break;
            }
        }
        Err(e) => println!("Error: {}", e),
    }
}
