error[E0005]: refutable pattern in local binding: `T(_, _)` not covered

|
|
| ^^^^^^^^^^^^ pattern `T(_, _)` 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
|
|
help: you might want to use `if let` to ignore the variant that isn't matched
