Assist: desugar doc-comment
My need for this arose due to wanting to do feature dependent documentation and therefor convert parts of my doc-comments to attributes.
Not sure about the pub-making of the other handlers functions, but I didn't think it made much sense to reimplement them.
Add action to expand a declarative macro once, inline. Fixes#13598
This commit adds a new r-a method, `expandMacroInline`, which expands the macro that's currently selected. See #13598 for the most applicable issue; though I suspect it'll resolve part of #5949 and make #11888 significantly easier).
The macro works like this:
I have 2 questions before this PR can be merged:
1. **Should we rustfmt the output?** The advantage of doing this is neater code. The disadvantages are we'd have to format the whole expr/stmt/block (since there's no point just formatting one part, especially over multiple lines), and maybe it moves the code around more in weird ways. My suggestion here is to start off by not doing any formatting; and if it appears useful we can decide to do formatting in a later release.
2. **Is it worth solving the `$crate` hygiene issue now?** -- I think this PR is usable as of right now for some use-cases; but it is annoying that many common macros (i.e. `println!()`, `format!()`) can't be expanded further unless the user guesses the correct `$crate` value. The trouble with solving that issue is that I think it's complicated and imperfect. If we do solve it; we'd also need to either change the existing `expandMacro`/`expandMacroInline` commands; provide some option to allow/disallow `$crate` expanding; or come to some other compromise.
fix: generate async delegate methods
Fixes a bug where the generated async method doesn't await the result before returning it.
This is an example of what the output looked like:
```rust
struct Age<T>(T);
impl<T> Age<T> {
pub(crate) async fn age<J, 'a>(&'a mut self, ty: T, arg: J) -> T {
self.0
}
}
struct Person<T> {
age: Age<T>,
}
impl<T> Person<T> {
pub(crate) async fn age<J, 'a>(&'a mut self, ty: T, arg: J) -> T {
self.age.age(ty, arg) // .await is missing
}
}
```
The `.await` is missing, so the return type is `impl Future<Output = T>` instead of `T`
add wrapping/checked/saturating assist
This addresses #13452
I'm not sure about the structure of the code. I'm not sure if it needs to be 3 separate assists, and if that means it needs to be in 3 separate files as well.
Most of the logic is in `util.rs`, which feels funny to me, but there seems to be a pattern of 1 assist per file, and this seems better than duplicating the logic.
Let me know if anything needs changes 😁

i'm aware of this repo's position on clippy. The changes are split into separate commits so they can be reviewed separately
