1034: HIR diagnostics API r=matklad a=matklad
This PR introduces diagnostics API for HIR, so we can now start issuing errors and warnings! Here are requirements that this solution aims to fulfill:
* structured diagnostics: rather than immediately rendering error to string, we provide a well-typed blob of data with error-description. These data is used by IDE to provide fixes
* open set diagnostics: there's no single enum with all possible diagnostics, which hopefully should result in better modularity
The `Diagnostic` trait describes "a diagnostic", which can be downcast to a specific diagnostic kind. Diagnostics are expressed in terms of macro-expanded syntax tree: they store pointers to syntax nodes. Diagnostics are self-contained: you don't need any context, besides `db`, to fully understand the meaning of a diagnostic.
Because diagnostics are tied to the source, we can't store them in salsa. So subsystems like type-checking produce subsystem-local diagnostic (which is a closed `enum`), which is expressed in therms of subsystem IR. A separate step converts these proto-diagnostics into `Diagnostic`, by merging them with source-maps.
Note that this PR stresses type-system quite a bit: we now type-check every function in open files to compute errors!

1036: Assist to flip equality (==) and negated equality (!=) operands. r=matklad a=marcogroppo
This PR adds an assist to flip the equality operands.
I hope this is the right way to do this (I'm a newbie...)
Fixes#1023.

991: Use Marker argument for item parsers r=matklad a=pcpthm
Before doing this for expressions, I found that the pattern (Marker argument) should be applied to the item parsers because visiblity and modifiers are parsed in a separate function.
Fixed some parser bugs:
- Fix pub_expr: `pub 42;` was allowed.
- Fix incorrect parsing of crate::path: incorrectly parsed as `crate` as a visibility.

983: support remainder assignment operator r=matklad a=JeanMertz
`%=` was returning errors for me, turns out it wasn't added as a valid assignment operation.
I'm not sure what the best location would be to add a test for this. Please let me know and I'll add one.

Benchmarks show no difference. This is probably because we are
bottlenecked on memory allocations, and we should fix that, but we are
not optimizing for performance just yet.

We allow invalid inner attributes to be parsed, e.g. inner attributes that are
not directly after the opening brace of the match block.
Instead we run validation on `MatchArmList` to allow better reporting of errors.
692: [WIP] Correctly parse attributes r=matklad a=DJMcNab
Reference - https://doc.rust-lang.org/reference/attributes.html
This fixes/investigates inner attributes for:
- [x] `impl` blocks
- [x] `extern` blocks
- [x] `fn`s (fixes#689)
- [x] `mod`s (already supported)
- [x] 'block expressions' (the long text just describes all 'blocks' used as statements)
This also investigates/fixes outer attributes for:
- [ ] 'most statements' (see also: #685, https://doc.rust-lang.org/reference/expressions.html#expression-attributes)
- [x] Enum variants, Struct and Union fields (Fixed in #507)
- [ ] 'Match expression arms' (@matklad can you provide a test case which explains what this means?)
- [ ] 'Generic lifetime or type parameters'
- [ ] 'Elements of array expressions, tuple expressions, call expressions, tuple-style struct and enum variant expressions'
- [ ] 'The tail expression of block expressions'

The new rowan uses arena allocator for red nodes which helps
slightly (5% on std completion test) with performance but should help
quite a bit with avoiding memory fragmentation.
630: Fill in DocumentSymbol::detail r=matklad a=hban
Closes: #516
I just pulled type text from the syntax node and "formatted" is bit. VS Code can't really handle multi-line symbol detail (it's will crop it when rendering), so that formatting will just collapse all white-space to singe space. It isn't pretty, but maybe there's a better way.
Issue also mentions "need to be done for `NavigationTarget` to `SymbolInformation`", but `SymbolInformation` doesn't have detail field on it?

623: WIP: module id is not def id r=matklad a=matklad
This achieves two things:
* makes module_tree & item_map per crate, not per source_root
* begins the refactoring to remove universal `DefId` in favor of having separate ids for each kind of `Def`. Currently, only modules get a differnt ID though.

440: Implement type inference for boolean operators r=flodiebold a=marcusklaas
Tried implementing the easiest part of https://github.com/rust-analyzer/rust-analyzer/issues/390. Hope this is somewhat close to what the intent of the issue was. Found it surprisingly easy to find my way around the repository - it's well organized!
Very grateful for any pointers.

This was a bit complicated. I've added a wrapper type for now that does the
LocalSyntaxPtr <-> ExprId translation; we might want to get rid of that or give
it a nicer interface.
Since we need to be able to go from def to containing impl block, as well as the
other direction, and to find all impls for a certain type, a design similar to
the one for modules, where we collect all impls for the whole crate and keep
them in an arena, seemed fitting. The ImplBlock type, which provides the public
interface, then consists only of an Arc to the arena containing all impls, and
the index into it.

We need to be able to get the receiver even if there is no field name yet, and
currently "a." wouldn't get parsed as a field name at all. This seems to help.
This improving this code is not a good use of people-time, and this
might be the most performant approach nonwithstanding
an api for this use case being added to walkdir
