Sad to be the one that does not get it.
Unwrap means it forces to evaluate the result as an ”ok value”. If it’s an ”error value”, it will crash. It’s a bad practice to rely on it, as it’s one of the most common ways a Rust programs can crash.
Rust offers many options to handle errors that don’t risk crashing. For example, unwrap_or_default, which means ”if it’s an error value, use the default value for this type, such as 0 for integers”
Unwrap is good for prototyping and trying out stuff fast, but it generally shouldn't make it past a code review onto main, unless you're very sure
