feat: Prioritize import suggestions based on the expected type
Hi, this is a draft PR to solve #15384. `Adt` types work and now I have a few questions :)
1. What other types make sense in this context? Looking at [ModuleDef](05666441ba/crates/hir/src/lib.rs (L275)) I am thinking everything except Modules.
2. Is there an existing way of converting between `ModeuleDef` and `hir::Type` in the rustanalyzer code base?
3. Does this approach seem sound to you?
Ups: Upon writing this I just realised that the enum test is invalided as there are no enum variants and this no variant is passed as a function argument.
Before
Private functions have RawVisibility module, but were
missed because take_types returned None early. After resolve_visibility
returned None, Visibility::Public was set instead and private functions
ended up being offered in autocompletion.
Choosing such a function results in an immediate error diagnostic
about using a private function.
After
Pattern match of take_types that returns None and
query for Module-level visibility from the original_module
Fix#15134 - tested with a unit test and a manual end-to-end
test of building rust-analyzer from my branch and opening
the reproduction repository
REVIEW
Refactor to move scope_def_applicable and check function visibility
from a module
Please let me know what's the best way to add a unit tests to
nameres, which is where the root cause was
fix: Insert fn call parens only if the parens inserted around field name
Fixes#16014.
Sorry I missed it in previous PR. I've added a test as level to prevent regressions again.
Give any suggestions to improve the test if anything.
TokenMap -> SpanMap rewrite
Opening early so I can have an overview over the full diff more easily, still very unfinished and lots of work to be done.
The gist of what this PR does is move away from assigning IDs to tokens in arguments and expansions and instead gives the subtrees the text ranges they are sourced from (made relative to some item for incrementality). This means we now only have a single map per expension, opposed to map for expansion and arguments.
A few of the things that are not done yet (in arbitrary order):
- [x] generally clean up the current mess
- [x] proc-macros, have been completely ignored so far
- [x] syntax fixups, has been commented out for the time being needs to be rewritten on top of some marker SyntaxContextId
- [x] macro invocation syntax contexts are not properly passed around yet, so $crate hygiene does not work in all cases (but most)
- [x] builtin macros do not set spans properly, $crate basically does not work with them rn (which we use)
~~- [ ] remove all uses of dummy spans (or if that does not work, change the dummy entries for dummy spans so that tests will not silently pass due to havin a file id for the dummy file)~~
- [x] de-queryfy `macro_expand`, the sole caller of it is `parse_macro_expansion`, and both of these are lru-cached with the same limit so having it be a query is pointless
- [x] docs and more docs
- [x] fix eager macro spans and other stuff
- [x] simplify include! handling
- [x] Figure out how to undo the sudden `()` expression wrapping in expansions / alternatively prioritize getting invisible delimiters working again
- [x] Simplify InFile stuff and HirFIleId extensions
~~- [ ] span crate containing all the file ids, span stuff, ast ids. Then remove the dependency injection generics from tt and mbe~~
