Here we have fixed the case where we were throwing two diagnostic
messages `E0026` and `E0027` for same case like this
Example
error[E0026]: variant `A::A` does not have a field named `fob`
--> src/test/ui/issue-52717.rs:20:12
|
20 | A::A { fob } => { println!("{}", fob); }
| ^^^ variant `A::A` does not have this field
error[E0027]: pattern does not mention field `foo`
--> src/test/ui/issue-52717.rs:20:5
|
20 | A::A { fob } => { println!("{}", fob); }
| ^^^^^^^^^^^^ missing field `foo`
error: aborting due to 2 previous errors
Here above we can see that both `E0026` and `E0027` are depicting
same thing.
So, to fix this issue, we are simply checking element of
`inexistent_fields` is there any value lies in
`unmentioned_fields` using Levenshtein algorithm, if does
then for that case we are simply deleting element from
`unmentioned_fields`. More or less now instead of showing
separate message in `E0027` we are giving extra hint on `E0026`
