Feat: hide double underscored symbols from symbol search
Fixes#17272 by changing the default behavior of query to skip results that start with `__` (two underscores).
Not sure if this has any far reaching implications - a review would help to understand if this is the right place to do the filtering, and if it's fine to do it by default on the query.
If you type `__` as your search, then we'll show the matching double unders, just in case you actually need the symbol.
Don't mark `#[rustc_deprecated_safe_2024]` functions as unsafe
`std::env::set_var` will be unsafe in edition 2024, but not before it. I couldn't quite figure out how to check for the span properly, so for now we just turn the false positives into false negatives, which are less bad.
Add `Function::fn_ptr_type(…)` for obtaining name-erased function type
The use case of this function if being able to group functions by their function ptr type.

fix: Only generate snippets for `extract_expressions_from_format_string` if snippets are supported
Part of #17332
Fixes `extract_expressions_from_format_string` so that it doesn't generate snippets if the client doesn't support it.

fix diagnostics clearing when flychecks run per-workspace
This might be causing #17300 or it's a different bug with the same functionality.
I wonder if the decision to clear diagnostics should stay in the main loop or maybe the flycheck itself should track it and tell the mainloop?
I have used a hash map but we could just as well use a vector since the IDs are `usizes` in some given range starting at 0. It would be probably faster but this just felt a bit cleaner and it allows us to change the ID to newtype later and we can just use a hasher that returns the underlying integer.
Add `toggle_async_sugar` assist code action
Implement code action for sugaring and de-sugaring asynchronous functions.
This code action does not import `Future` trait when de-sugaring and does not touch function boby, I guess this can be implemented later if needed. This action also does not take into consideration other bounds because IMO it's usually "let me try to use sugared version here".
Feel free to request changes, that's my first code action implementation 😄Closes#17010
Relates to #16195
Implement assist to switch between doc and normal comments
Hey first PR to rust-analyzer to get my feet wet with the code base. It's an assist to switch a normal comment to a doc comment and back, something I've found myself doing by hand a couple of times.
I shamelessly stole `relevant_line_comments` from `convert_comment_block`, because I didn't see any inter-assist imports happening in the files I peeked at so I thought this would be preferable.
Fix `data_constructor` ignoring generics for struct
Previously didn't work for structs with generics due to `field.ty()` having placeholders in type.
_Enums were handeled correctly already._
Also renamed `type_constructor -> data_constructor` as this is more correct name for it
Allow sysroots to only consist of the source root dir
Fixes https://github.com/rust-lang/rust-analyzer/issues/17159
This PR encodes the `None` case of an optional sysroot into `Sysroot` itself. This simplifies a lot of things and allows us to have sysroots that consist of nothing, only standard library sources, everything but the standard library sources or everything. This makes things a lot more flexible. Additionally, this removes the workspace status bar info again, as it turns out that that can be too much information for the status bar to handle (this is better rendered somewhere else, like in the status view).
Fix: infer type of async block with tail return expr
Fixes#17106
The `infer_async_block` method calls the `infer_block` method internally, which returns the never type without coercion when `tail_expr` is `None` and `ctx.diverges` is `Diverges::Always`.This is the reason for the bug in this issue.
cfce2bb46d/crates/hir-ty/src/infer/expr.rs (L1411-L1413)
This PR solves the bug by adding a process to coerce after calling `infer_block` method.
This code passes all the tests, including tests I added for this isuue, however, I am not sure if this solution is right. I think that this solution is an ad hoc solution. So, I would appreciate to have your review.
I apologize if I'm off the mark, but `infer_async_block` method should be rewritten to share code with the process of infering type of `expr::Closure` instead of the `infer_block` method. That way it will be closer to the infer process of rustc.
handle {self} when removing unused imports
Fixes#17139
On master
```rs
mod inner {
pub struct X();
pub struct Y();
}
mod z {
use super::inner::{self, X}$0;
fn f() {
let y = inner::Y();
}
}
```
becomes
```rs
mod inner {
pub struct X();
pub struct Y();
}
mod z {
use super::inner:self;
fn f() {
let y = inner::Y();
}
}
```
with this fix it instead becomes
```
```rs
mod inner {
pub struct X();
pub struct Y();
}
mod z {
use super::inner;
fn f() {
let y = inner::Y();
}
}
```
fix: ensure implied bounds from associated types are considered in autocomplete
closes: #16989
rust-analyzer needs to consider implied bounds from associated types in order to get all methods suggestions people expect. A pretty easy way to do that is to keep the `candidate_trait_id`'s receiver if it matches `TyFingerprint::Unnameable`. When benchmarking this change, I didn't notice a meaningful difference in autocomplete latency.
(`TyFingerprint::Unnameable` corresponds to `TyKind::AssociatedType`, `TyKind::OpaqueType`, `TyKind::FnDef`, `TyKind::Closure`, `TyKind::Coroutine`, and `TyKind::CoroutineWitness`.)
Clear diagnostics only after new ones were received
Closes#15934
This adds a flag inside the global state which controls when old diagnostics are cleared. Now, old diagnostics should be cleared only after at least one new diagnostic is available.
feat: More callable info
With this PR we retain more info about callables other than functions, allowing for closure parameter type inlay hints to be linkable as well as better signature help around closures and `Fn*` implementors.
