Akousapanic-unwrapThe program panicked because unwrap() was called on a None or Err value.
unwrap() is called on an Option that is None or a Result that is Err. This is a runtime error that crashes the program. It indicates the code assumed a value would always be present, but it was not.
Use match or if let to handle None and Err cases gracefully. Use unwrap_or(), unwrap_or_default(), or unwrap_or_else() to provide fallback values. Use the ? operator to propagate errors instead of panicking.
let x: Option<i32> = None;
x.unwrap(); // panics!clippy::clone_on_copyThe clone() method is called on a type that implements Copy.
