| LL | Err(#[stable(feature = "rust1", since = "1.0.0")] E), |
| | --- not covered |
| | |
| = note: `let` bindings require an "irrefutable pattern", like a `struct` or an `enum` with only one variant |
| = note: for more information, visit https://doc.rust-lang.org/book/ch18-02-refutability.html |
| = note: the matched value is of type `std::result::Result<u32, &R>` |
| help: you might want to use `if let` to ignore the variant that isn't matched |
