3632: ra_cargo_watch: log errors r=matklad a=Veetaha
Until this moment we totally ignored all the errors from cargo process. Though this is still true, but we
now try to log ones that are critical (i.e. misconfiguration errors and ignore compile errors).
This fixes#3631, and gives us a better error message to more gracefully handle the #3265
Though I think that outputting this only to `Output` channel is not enough. We should somehow warn the user that he passed wrong arguments to `cargo-watch.args`. I didn't bother looking for how to do this now, but this PR at least gives us something.

As stated by matklad, reading the stderr
should be done alngside with
stdout via select() (or I guess poll()),
there is no such implementation in stdlib,
since it is quite low level and platform-dependent and it
also requires quite a bit of unrelated code we don't use it for now.
As referenced by bjorn3, there is an implementation of the needed read2() function
in rustc compiletest. The better solution will be to extract this function
to a separate crate in future:

3671: Add identity expansion checking in ill-form expansion r=flodiebold a=edwin0cheng
This PR try to add more checking code in error case in macro expansion. The bug in #3642 is introduced by #3580 , which allow ill-form macro expansion in *all* kind of macro expansions.
In general we should separate hypothetical macro expansion and the actual macro expansion call. However, currently the `Semantic` workflow we are using only support single macro expansion type, we might want to review it and make it works in both ways. (Maybe add a field in `MacroCallLoc` for differentiation)

3623: 'Fill match arms' should work with existing match arms r=matklad a=slyngbaek
Addresses #3039
This essentially adds missing match arms. The algorithm for this
can get complicated rather quickly so bail in certain conditions
and rely on a PlaceholderPat.
The algorighm works as such:
- Iterate through the Enum Def Variants
- Attempt to see if the variant already exists as a match arm
- If yes, skip the enum variant. If no, include it.
- If it becomes complicated, rather than exhaustively deal with every
branch, mark it as a "partial match" and simply include the
placeholder.
Conditions for "complication":
- The match arm contains a match guard
- Any kind of nested destrucuring
Order the resulting merged match branches as such:
1. Provided match arms
2. Missing enum variant branch arms
3. End with Placeholder if required
- Add extra tests

Iterate through TupleStructPat's until a MatchArm if
one exists. Store in a new is_pat_bind_and_path bool
and allow the `complete_scope` to find matches.
Added some tests to ensure it works in simple and nested cases.

It improves compile time in `--release` mode quite a bit, it doesn't
really slow things down and, conceptually, it seems closer to what we
want the physical architecture to look like (we don't want to
monomorphise EVERYTHING in a single leaf crate).
3573: Check all crates of the workspace r=matklad a=matklad

Ideally, we might want some kind of config here (which might be just

3591: Support local macro_rules r=matklad a=edwin0cheng
This PR implement local `macro_rules` in function body, by adding following things:
1. While lowering, add a `MacroDefId` in body's `ItemScope` as a textual legacy macro.
2. Make `Expander::enter_expand` search with given `ItemScope`.
3. Make `Resolver::resolve_path_as_macro` search with `LocalItemScope`.

3577: Protect against infinite macro expansion in def collector r=edwin0cheng a=flodiebold
Something I noticed while trying to make macro expansion more resilient against errors.
There was a test for this, but it wasn't actually working because the first recursive expansion failed. (The comma...)
Even with this limit, that test (when fixed) still takes some time to pass because of the exponential growth of the expansions, so I disabled it and added a different one without growth.

The `ty` function in code_model returned the type with placeholders for type
parameters. That's nice for printing, but not good for completion, because
placeholders won't unify with anything else: So the type we got for `HashMap`
was `HashMap<K, V, T>`, which doesn't unify with `HashMap<?, ?, RandomState>`,
so the `new` method wasn't shown.
Now we instead return `HashMap<{unknown}, {unknown}, {unknown}>`, which does
unify with the impl type. Maybe we should just expose this properly as variables
though, i.e. we'd return something like `exists<type, type, type> HashMap<?0,
?1, ?2>` (in Chalk notation). It'll make the API more complicated, but harder to
misuse. (And it would handle cases like `type TypeAlias<T> = HashMap<T, T>` more
correctly.)
Previously, if the root of the was was a real crate, only this crate
was checked.

3553: Completions do not show for function with same name as mod r=matklad a=JoshMcguigan
fixes#3444
I've added a test case in `crates/ra_ide/src/completion/complete_path.rs` which verifies the described behavior in #3444. Digging in, I found that [the module scope iterator](ba62d8bd1c/crates/ra_ide/src/completion/complete_path.rs (L22)) only provides the module `z`, and does not provide the function `z` (although if I name the function something else then it does show up here).
I thought perhaps the name wasn't being properly resolved, but I added a test in `crates/ra_hir_def/src/nameres/tests.rs` which seems to suggest that it is? I've tried to figure out how to bridge the gap between these two tests (one passing, one failing) to see where the function `z` is being dropped, but to this point I haven't been able to track it down.
Any pointers on where I might look for this?

3564: Better handling of a few kinds of cargo/clippy diagnostics r=matklad a=kiljacken
This was initially supposed to just be a fix for #3433, but I caught a few things that ended up being useful as well.
This PR primarily makes us handle multi-edit fix suggestions properly. Instead of just applying the first fix we apply all the parts of the fix in a single action.
Second up, this PR handles diagnostics with multiple primary spans, f.x. the unused import diagnostic from rustc:
The LSP doesn't handle this too well, as it only support a single complete range for each diagnostic, so we get duplicate messages in the problem panel of VSCode:
However, I feel like the improved visual aspect in-editor outweighs the duplication in the problem panel. I'm open to not including the second commit if anybody really doesn't like the idea of duplicate diagnostics in the problem pane.

3549: Implement env! macro r=matklad a=edwin0cheng
This PR implements `env!` macro by adding following things:
1. Added `additional_outdirs` settings in vscode. (naming to be bikeshed)
2. Added `ExternSourceId` which is a wrapping for SourceRootId but only used in extern sources. It is because `OUT_DIR` is not belonged to any crate and we have to access it behind an `AstDatabase`.
3. This PR does not implement the `OUT_DIR` parsing from `cargo check`. I don't have general design about this, @kiljacken could we reuse some cargo watch code for that ?
~~Block on [#3536]~~
PS: After this PR , we (kind of) completed the `include!(concat!(env!('OUT_DIR'), "foo.rs")` macro call combo. [Exodia Obliterate!](https://www.youtube.com/watch?v=RfqNH3FoGi0)

3542: Renames work on struct field shorthands r=matklad a=m-n
When renaming either a local or a struct field, struct field shorthands are now renamed correctly.
Happy to refactor this if it doesn't fit the design of the code. Thanks for adding the suggestion of where to start on the issue.
I wasn't sure if I should also look at the behavior of renaming when placing the cursor at the field shorthand; the following describes the behavior with this patch:
```rust
#[test]
fn test_rename_field_shorthand_for_unspecified() {
// when renaming a shorthand, should we have a way to specify
// between renaming the field and the local?
//
// If not is this the correct default?
test_rename(
r#"
struct Foo {
i: i32,
}
impl Foo {
fn new(i: i32) -> Self {
Self { i<|> }
}
}
"#,
"j",
r#"
struct Foo {
i: i32,
}
impl Foo {
fn new(j: i32) -> Self {
Self { i: j }
}
}
"#,
);
}
```

- Updated naming of config
- Define struct in ra_ide and use remote derive in rust-analyzer/config
- Make inlayConfig type more flexible to support more future types
- Remove constructor only used in tests
Add setting to allow enabling either type inlay hints or parameter
inlay hints or both. Group the the max inlay hint length option
into the object.
- Add a new type for the inlayHint options.
- Add tests to ensure the inlays don't happen on the server side
To test whether the receiver type matches for the impl, we unify the given self
type (in this case `HashSet<{unknown}>`) with the self type of the
impl (`HashSet<?0>`), but if the given self type contains Unknowns, they won't
be unified with the variables in those places. So we got a receiver type that
was different from the expected one, and concluded the impl doesn't match.
The fix is slightly hacky; if after the unification, our variables are still
there, we make them fall back to Unknown. This does make some sense though,
since we don't want to 'leak' the variables.
Fixes#3547.
