9808: fix: Look for enum variants and trait assoc functions when looking for lang items r=matklad a=Veykril
Examples for lang enum variants are the `Option` variants.
Assoc trait functions aren't being seen since they aren't declared in the direct module scope.

9764: fix: Don't use the module as the candidate node in fuzzy path flyimport r=Veykril a=Veykril

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.

Some features of rust-analyzer requires support for custom commands on
the client side. Specifically, hover & code lens need this.
Stock LSP doesn't have a way for the server to know which client-side
commands are available. For that reason, we historically were just
sending the commands, not worrying whether the client supports then or
not.
That's not really great though, so in this PR we add infrastructure for
the client to explicitly opt-into custom commands, via `extensions`
field of the ClientCapabilities.
To preserve backwards compatability, if the client doesn't set the
field, we assume that it does support all custom commands. In the
future, we'll start treating that case as if the client doesn't support
commands.
So, if you maintain a rust-analyzer client and implement
`rust-analyzer/runSingle` and such, please also advertise this via a
capability.

9700: fix: Remove the legacy macro scoping hack r=matklad a=jonas-schievink
This stops prepending `self::` to single-ident macro paths, resolving even legacy-scoped macros using the fixed-point algorithm. This is not correct, but a lot easier than fixing this properly (which involves pushing a new scope for every macro definition and invocation).
This allows resolution of macros from the prelude, fixing https://github.com/rust-analyzer/rust-analyzer/issues/9687.

9558: Do not erase Cargo diagnostics from the closed documents r=matklad a=SomeoneToIgnore
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/6850
The LSP specification at https://microsoft.github.io/language-server-protocol/specifications/specification-3-14/#textDocument_publishDiagnostics states that
> Diagnostics notification are sent from the server to the client to signal results of validation runs.
>
> Diagnostics are “owned” by the server so it is the server’s responsibility to clear them if necessary. The following rule is used for VS Code servers that generate diagnostics:
>
> * if a language is single file only (for example HTML) then diagnostics are cleared by the server when the file is closed.
> * if a language has a project system (for example C#) diagnostics are not cleared when a file closes. When a project is opened all diagnostics for all files are recomputed (or read from a cache).
>
> When a file changes it is the server’s responsibility to re-compute diagnostics and push them to the client. If the computed set is empty it has to push the empty array to clear former diagnostics. Newly pushed diagnostics always replace previously pushed diagnostics. There is no merging that happens on the client side.
So for projects we should not clear any diagnostics from cargo/json projects.
Our "standalone file" mode is in a way a project too, with sysroot attached and a potential support for dynamic standalone files.

This adds `CompletionContext::is_visible` as a convenience method that checks visibility, presence of `doc(hidden)`, and whether the completed item is in the same crate as the completion site or not. We only complete `doc(hidden)` items from the same crate.
This doesn't yet work for *all* completions: `qualified_path` completions use `Module::scope` and `ScopeDef`, which doesn't work with this.

9453: Add first-class limits. r=matklad,lnicola a=rbartlensky
Partially fixes#9286.
This introduces a new `Limits` structure which is passed as an input
to `SourceDatabase`. This makes limits accessible almost everywhere in
the code, since most places have a database in scope.
One downside of this approach is that whenever you query limits, you
essentially do an `Arc::clone` which is less than ideal.
Let me know if I missed anything, or would like me to take a different approach!

Our project model code is rather complicated -- the logic for lowering
from `cargo metadata` to `CrateGraph` is fiddly and special-case. So
far, we survived without testing this at all, but this increasingly
seems like a poor option.
So this PR introduces a simple tests just to detect the most obvious
failures. The idea here is that, although we rely on external processes
(cargo & rustc), we are actually using their stable interfaces, so we
might just mock out the outputs.
Long term, I would like to try to virtualize IO here, so as to do such
mocking in a more principled way, but lets start simple.
Should we forgo the mocking and just call `cargo metadata` directly
perhaps? Touch question -- I personally feel that fast, in-process tests
are more important in this case than any extra assurance we get from
running the real thing.
Super-long term, we would probably want to extend our heavy tests to
cover more use-cases, but we should figure a way to do that without
slowing the tests down for everyone.
Perhaps we need two-tiered bors system, where we pull from `master` into
`release` branch only when an additional set of tests passes?

9600: fix: Single-line and nested blocks in the `unwrap_block` assist r=Veykril a=patrick-gu
Fixes#8411
Rework the system for stripping whitespace and braces in the unwrap_block assist to allow correct unwrapping of blocks such as:
```rust
{ $0 0 }
```
into
```rust
0
```
and nested blocks, such as:
```rust
$0{
{
3
}
}
```
into
```rust
{
3
}
```
This is done by creating the `update_expr_string_with_pat` function (along with `update_expr_string` and `update_expr_string_without_newline`), which strips whitespace and braces in a way that ensures that only whitespace and a maximum of one brace are removed from the start and end of the expression string.
I have also created several tests to ensure that this functionality works correctly.

9550: Proc macro multi abi proof of concept r=matklad a=alexjg
#8925 was irritating me so I thought I would have a bash at fixing it. What I've done here is copy the `crates/proc_macro_srv/src/proc_macro` code (which is copied from `<RUST>/library/proc_macro`) to `crates/proc_macro_srv/src/proc_macro_nightly` and the modified the nightly version to include the changes from https://github.com/rust-analyzer/rust-analyzer/pull/9047 and aeb7b183a2
This gives us the code to support both stable and nightly ABIs. Then we use the `proc_macro_api::version::read_dylib_info` to determine which version of the ABI to load when creating a `ProcMacroLibraryLibLoading` (which is now an enum).
This seems to work for me. The code could be cleaned up but I wanted to see if the approach makes sense before I spend more time on it.
I've split the change into two commits, the first is just copying and modifying the `proc_macro` crate, the second contains most of the interesting work around figuring out which ABI to use.
