### What it does Checks for `.or(…).unwrap()` calls to Options and Results. ### Why is this bad? You should use `.unwrap_or(…)` instead for clarity. ### Example ``` // Result let value = result.or::(Ok(fallback)).unwrap(); // Option let value = option.or(Some(fallback)).unwrap(); ``` Use instead: ``` // Result let value = result.unwrap_or(fallback); // Option let value = option.unwrap_or(fallback); ```
