PR #82639 changed UI tests so `-Z unstable-options` aren't passed to UI tests by default. This completely broke `use_suggestion_json.rs`, which uses the unstable `--error-format=pretty-json` option. The expected output went from 400 lines of pretty JSON error messages to a single JSON error saying "`--error-format=pretty-json` is unstable"! This commit adds `-Z unstable-options` back and reinstates the old expected output, with some minor changes to account for shifted spans and slightly JSON output changes since then.

"message": "cannot find type `Iter` in this scope",

"code": {
|
|
"code": "E0412",
|
|
"explanation": "A used type name is not in scope.
|
|
|
|
Erroneous code examples:
|
|
|
|
```compile_fail,E0412
|
|
impl Something {} // error: type name `Something` is not in scope
|
|
|
|
// or:
|
|
|
|
trait Foo {
|
|
fn bar(N); // error: type name `N` is not in scope
|
|
}
|
|
|
|
// or:
|
|
|
|
fn foo(x: T) {} // type name `T` is not in scope
|
|
```
|
|
|
|
To fix this error, please verify you didn't misspell the type name, you did
|
|
declare it or imported it into the scope. Examples:
|
|
|
|
```
|
|
struct Something;
|
|
|
|
impl Something {} // ok!
|
|
|
|
// or:
|
|
|
|
trait Foo {
|
|
type N;
|
|
|
|
fn bar(_: Self::N); // ok!
|
|
}
|
|
|
|
// or:
|
|
|
|
fn foo<T>(x: T) {} // ok!
|
|
```
|
|
|
|
Another case that causes this error is when a type is imported into a parent
|
|
module. To fix this, you can follow the suggestion and use File directly or
|
|
`use super::File;` which will import the types from the parent namespace. An
|
|
example that causes this error is below:
|
|
|
|
```compile_fail,E0412
|
|
use std::fs::File;
|
|
|
|
mod foo {
|
|
fn some_function(f: File) {}
|
|
}
|
|
```
|
|
|
|
```
|
|
use std::fs::File;
|
|
|
|
mod foo {
|
|
// either
|
|
use super::File;
|
|
// or
|
|
// use std::fs::File;
|
|
fn foo(f: File) {}
|
|
}
|
|
# fn main() {} // don't insert it for us; that'll break imports
|
|
```
