Previously, we only inverted comparison operators (< and the like) if
the type implemented Ord. This doesn't make sense: if `<` works, then
`>=` will work as well!
Extra semantic checks greatly reduce robustness and predictability of
the assist, it's better to keep things simple.
9871: Jump to generated func r=mahdi-frms a=rylev
Worked on this with `@yoshuawuyts.`
We thought we ran into an issue with the `generate_function` assist where the code was not being generated in a certain situations. However, it wasn't actually a bug just a very confusing implementation where the cursor is not moved to the newly generated function. This happened when the return type was successfully inferred (and not unit). The function would be generated, but selection would not be changed.
This can be very confusing: If the function is generated somewhat far from where the assist is being invoked, the user never sees that the code was generated (nor are they given the chance to actually implement the function body).
This PR makes it so that the cursor is _always_ moved to somewhere in the newly generated function. In addition, if we can infer unit as the type, then we do not still generate `-> ()` as the return type. Instead, we simply omit the return type.
This means the selection will move to either one of two places:
* A generated `-> ()` return type when we cannot successfully infer the return type.
* The `todo!()` body when we can successfully infer the return type.

9836: Refactor: quick clean-up of iteration idioms in the `vfs` crate r=matklad a=Some-Dood
This PR cleans up some of the iteration idioms used in the `vfs` crate. Most of the changes simply converted `for` loops into their `std::iter::Iterator`-method counterpart. Other changes required some inversion of logic to accommodate for better short-circuiting. Overall, there should be no behavioral changes. If there are any stylistic issues, I will gladly adhere to them and adjust the PR accordingly. Thanks!

9828: Remove dependency on the system graphviz when rendering crate graph r=lnicola a=p32blo
This PR removes the need for having `graphviz` installed on the user system by using the `d3-graphviz` npm package.
The responsibility of rendering the svg output is moved to the extension while the rust side only handles the generation of the dot file.
This change also brings the following additional features:
- Allow zooming the view
- Ctrl+click to reset the zoom
- Adjust the color scheme to dark themes
- Works on any platform without installing graphviz locally
---
I’m not sure if this fits what you had in mind for the crates graph feature but I decided to submit it anyway to see if this is useful to anyone else.
A potential downside might be that it increases the extension size ( haven’t checked) but this feature already required the installation of graphviz on the user side, so the cost is just moved explicitly to the extension.
Feel free to make any suggestion or comments.

9825: Generate default impl when converting #[derive(Default)] to manual impl r=Veykril a=yoshuawuyts
Similar to https://github.com/rust-analyzer/rust-analyzer/pull/9814, but for `#[derive(Default)]`. Thanks!
## Follow-up steps
I've added the tests inside `handlers/replace_derive_with_manual_impl.rs` again, but I'm planning a follow-up PR to extract these to `utils/` so we can share them between assists - and maybe even add another assist just for the purpose of testing these impls (e.g. `generate_default_trait_body`).
The step after _that_ is likely to fill out the remaining traits, so we can make it so whenever RA auto-completes a trait which also can be derived, we provide a default function body.

From the dawn of time, when dinosaurs roamed the and we didn't have
hierarchical profiling, there was the `latest_requests` infra we used to
track the time of ten last requests.
Today, no one is actually using it and, what's more, it itself became
pretty useless -- LSP grew way more chatty, and 10 requests don't really
paint any kind of picture.
Personally, it's been years since I last looked at latest requests in
the status output.
So, let's remove a tiny bit of state from the big ball of complexity
that is `GlobalState` and `main_loop`!
Today, rust-analyzer (and rustc, and bat, and IntelliJ) fail badly on
some kinds of maliciously constructed code, like a deep sequence of
nested parenthesis.
"Who writes 100k nested parenthesis" you'd ask?
Well, in a language with macros, a run-away macro expansion might do
that (see the added tests)! Such expansion can be broad, rather than
deep, so it bypasses recursion check at the macro-expansion layer, but
triggers deep recursion in parser.
In the ideal world, the parser would just handle deeply nested structs
gracefully. We'll get there some day, but at the moment, let's try to be
simple, and just avoid expanding macros with unbalanced parenthesis in
the first place.
closes#9358
We generally avoid "syntax only" helper wrappers, which don't do much:
they make code easier to write, but harder to read. They also make
investigations harder, as "find_usages" needs to be invoked both for the
wrapped and unwrapped APIs
9814: Generate default impl when converting `#[derive(Debug)]` to manual impl r=yoshuawuyts a=yoshuawuyts
This patch makes it so when you convert `#[derive(Debug)]` to a manual impl, a default body is provided that's equivalent to the original output of `#[derive(Debug)]`. This should make it drastically easier to write custom `Debug` impls, especially when all you want to do is quickly omit a single field which is `!Debug`.
This is implemented for enums, record structs, tuple structs, empty structs - and it sets us up to implement variations on this in the future for other traits (like `PartialEq` and `Hash`).
Thanks!
## Codegen diff
This is the difference in codegen for record structs with this patch:
```diff
struct Foo {
bar: String,
}
impl fmt::Debug for Foo {
fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
- todo!();
+ f.debug_struct("Foo").field("bar", &self.bar).finish()
}
}
```

9764: fix: Don't use the module as the candidate node in fuzzy path flyimport r=Veykril a=Veykril
The problem was that the candidate node is whats being used for the scope, so using an inline module will yield the surrounding scope of the module instead of the scope of the module itself.
Also seems to fix the problem in this comment https://github.com/rust-analyzer/rust-analyzer/issues/9760#issuecomment-891125674, though I could not recreate that in a test for some reason.

9751: Make `LoadCargoConfig`, `fn load_workspace_at` & `fn load_workspace` public again r=matklad a=regexident
This [commit](b24f816c0d) which restricted the visibility of `LoadCargoConfig`, `fn load_workspace_at` & `fn load_workspace` unfortunately effectively rendered every crate/tool that uses rust-analyzer as a library dead in the water.
On of such tools is [cargo-modules](https://github.com/regexident/cargo-modules), a tool for generating tree/graph visualizations of one's Rust project and is powered by rust-analyzer as a library.
For more context see the PRs that introduced those types/functions and made them `pub`:
- https://github.com/rust-analyzer/rust-analyzer/pull/7595
- https://github.com/rust-analyzer/rust-analyzer/pull/7690
If kept as is rust-analyzer would effectively no longer be usable as a library.

9752: feature: Declare proc-macro dependent crates in `rust-project.json` r=matklad a=tobywf
This adds the `is_proc_macro` flag in `rust-project.json`. By default, this is `false` and not required, so existing projects won't break/have the same behavior as before this change. If the flag is true, a dependency to the `proc_macro` sysroot crate is added (if it exists), so that rust-analyzer can resolve those imports.
This fixes#9726 .
I've also added some tests in the second commit. The first is a smoke test for a basic, minimal `rust-project.json` file. The second is a more targeted test for the flag. Both tests depend on the fake sysroot (a bunch of directories in the correct layout with empty `lib.rs` files), and also on `env!("CARGO_MANIFEST_DIR")` being an absolute path. I'm not sure if the later assumption is valid on all platforms. I wanted to at least try and add tests, but I'm happy to rework them or remove them if you don't think that's the way to go.
