As an example:
#[test]
#[ignore = "not yet implemented"]
fn test_ignored() {
...
}
Will now render as:
running 2 tests
test tests::test_ignored ... ignored, not yet implemented
test result: ok. 1 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 0.00s
Add more info and suggestions to use of #[test] on invalid items
This pr changes the diagnostics for using `#[test]` on an item that can't be used as a test to explain that the attribute has no meaningful effect on non-functions and suggests the use of `#[cfg(test)]` for conditional compilation instead.
Example change:
```rs
#[test]
mod test {}
```
previously output
```
error: only functions may be used as tests
--> src/lib.rs:2:1
|
2 | mod test {}
| ^^^^^^^^^^^
```
now outputs
```
error: the `#[test]` attribute may only be used on a non-associated function
--> $DIR/test-on-not-fn.rs:3:1
|
LL | #[test]
| ^^^^^^^
LL | mod test {}
| ----------- expected a non-associated function, found a module
|
= note: the `#[test]` macro causes a a function to be run on a test and has no effect on non-functions
help: replace with conditional compilation to make the item only exist when tests are being run
|
LL | #[cfg(test)]
| ~~~~~~~~~~~~

TraitKind -> Trait
TyAliasKind -> TyAlias
ImplKind -> Impl
FnKind -> Fn
All `*Kind`s in AST are supposed to be enums.
Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order.
Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.
