A tuple struct or tuple variant was used in a pattern as if it were a struct or
struct variant.
Erroneous code example:
```compile_fail,E0769
enum E {
A(i32),
}
let e = E::A(42);
match e {
E::A { number } => { // error!
println!("{}", number);
}
}
```
To fix this error, you can use the tuple pattern:
```
# enum E {
# A(i32),
# }
# let e = E::A(42);
match e {
E::A(number) => { // ok!
println!("{}", number);
}
}
```
Alternatively, you can also use the struct pattern by using the correct field
names and binding them to new identifiers:
```
# enum E {
# A(i32),
# }
# let e = E::A(42);
match e {
E::A { 0: number } => { // ok!
println!("{}", number);
}
}
```
