This basically says "Give +`unwrap()` will `panic!` if the `Result` is `Err`. This basically says "Give me the value, and if something goes wrong, just crash." This is less reliable than matching the error and attempting to recover, but is also significantly shorter. Sometimes, just crashing is appropriate. |
