What happens here is that we lower `: ` to a missing expression, and
then correctly record that the corresponding field expression resolves
to a specific field. Where we fail is in the mapping of syntax to this
missing expression. Doing it via `ast_field.expr()` fails, as that
expression is `None`. Instead, we go in the opposite direcition and ask
each lowered field about its source.
This works, but has wrong complexity `O(N)` and, really, the
implementation is just too complex. We need some better management of
data here.

7335: added region folding r=matklad a=LucianoBestia
Regions of code that you'd like to be folded can be wrapped with `// #region` and `// #endregion` line comments.
This is called "Region Folding". It is originally available for many languages in VSCode. But Rust-analyzer has its own folding function and this is missing.
With this Pull Request I am suggesting a simple solution.
The regions are a special kind of comments, so I added a bit of code in the comment folding function.
The regex to match are: `^\s*//\s*#?region\b` and `^\s*//\s*#?endregion\b`.
The number of space characters is not important. There is an optional # character. The line can end with a name of the region.
Example:
```rust
// 1. some normal comment
// region: test
// 2. some normal comment
calling_function(x,y);
// endregion: test
```
I added a test for this new functionality in `folding_ranges.rs`.
Please, take a look and comment.
I found that these exact regexes are already present in the file `language-configuration.json`, but I don't find a way to read this configuration. So my regex is hardcoded in the code.
7691: Suggest name in extract variable r=matklad a=cpud36
Generate better default name in extract variable assist as was mentioned in issue #1587
# Currently supported
(in order of declining precedence)
1. Expr is argument to a function; use corresponding parameter name
2. Expr is result of a function or method call; use this function/method's name
3. Use expr type name (if possible)
4. Fallback to `var_name` otherwise
# Showcase
# Questions
* Should we more aggressively strip known types? E.g. we already strip `&T -> T`; should we strip `Option<T> -> T`, `Result<T, E> -> T`, and others?
* Integers and floats use `var_name` by default. Should we introduce a name, like `i`, `f` etc?
* Can we return a list and suggest a name when renaming(like IntelliJ does)?
* Should we add counters to remove duplicate variables? E.g. `type`, `type1`, type2`, etc.

7732: Don't lower TypeBound::Lifetime as GenericPredicate::Error r=flodiebold a=Veykril
Basically we just discard the typebound for now instead when lowering to `GenericPredicate`. I think this shouldn't have any other side effects?
Fixes #7683(hopefully for real this time)
I also played around with introducing `GenericPredicate::LifetimeOutlives` and `GenericPredicate::TypeOutlives`(see b9d6904845) but that won't fix this issue(at least not for now) due to lifetime predicate mismatches when resolving methods so I figure this is a good way to fix it for now.

7699: Implement ast::AstNode for NameLike and move it to node_ext r=matklad a=Veykril
With this `search`(and 2 other modules) don't necessarily go through 3 calls of `find_node_at_offset_with_descend` to find the correct node. Also makes the code that searches for NameLikes a bit easier on the eyes imo, though that can be fixed with just a helper function as well so its not that relevant.

7656: Implement constructor usage search for almost all items r=matklad a=Veykril
This PR moves the filering for enum constructors to the HIR, with this unprefixed variants as well as when the enum has been renamed via use will then still show up properly.
We now walk the ast of the `NameRef` up until we find a `PathExpr`(which also handles `CallExpr` for tuple-type structs and variants already) or a `RecordExpr`. For enum search we then take the `path` out of that expression and do a resolution on it to compare it with the definition enum.
With this PR we now support searching for all constructor literals, Unit-, Tuple- and Record-Structs, Unit-, Tuple- and Record-Variants as well as Unions.
There is one shortcoming due to how the search is triggered. Unit Variants constructors can't be searched as we have no position for it to kick off the search(since a comma doesn't have to exist for the last variant).
Closes#2549 though it doesn't implement it as outlined in the issue since the reference kind was removed recently, though I believe the approach taken here is better personally.

7668: Finalize rename infra rewrite r=matklad a=Veykril
This should be the final PR in regards to rewriting rename stuff, #4290.
It addresses 3 things:
- Currently renaming import aliases causes some undesired behavior(see #5198) which is why this PR causes us to just return an error if an attempt at renaming an alias is made for the time being. Though this only prevents it from happening when the alias import is renamed, so its not too helpful.
- Fixes#6898
- If we are inside a macro file simply rename the input name node as there isn't really a way to do any of the fancy shorthand renames and similar things as for that we would have to exactly know what the macro generates and what not.
Co-authored-by: Lukas Wirth <lukastw97@gmail.com>
For all struct kinds, unions and enums, as well as for record- and
tuple-variants but not for unit-variants, as these have no trailing
character we can anchor the search to. Functionality wise it is
implemented though.

7353: Add LifetimeParam and ConstParam to CompletionItemKind r=matklad a=Veykril
Adds `LifetimeParam` and `ConstParam` to `CompletionItemKind` and maps them both to `TypeParam` in the protocol conversion as there are no equivalents, so nothing really changes there.
`ConstParam` could be mapped to `Const` I guess but I'm split on whether that would be better?
Additions were solely inspired by (the single) test output for const params.
Also sorts the variants of `CompletionItemKind` and its to_proto match.

Open question would be the name of the delimiter modifiers. I chose them this was as I see them this way but from what I remember people tend to mix the names however they like.

7224: Remove unnecessary allocation when checking whether to hide argument name hint r=jhpratt a=jhpratt
The case-insensitive prefix/suffix check can be performed
character-by-character. This allows the check to be done without having
to allocate a new string. As a side effect, it's also no longer
necessary to convert the entire string to lowercase, as it's done as
needed. As the only case equality we're handling is ASCII, this
operation can be further optimized by using byte equality, rather than
character equality.

This leaks a lot of LSP details into ide layer, which we want to avoid:
c9cec381bc/docs/dev (lsp-independence)
Additionally, all what this infra does is providing a toggle for
auto-import completion, but we already have one!
Rather than eagerly converting JSON, we losslessly keep it as is, and
change the shape of user-submitted data at the last moment.

In #6901 some special case handling for proc-macros was introduced to
prevent panicing as they have no AST. Now the new HasSource::source
method is used that returns an option.
Generally this was a pretty trivial change, the only thing of much
interest is that `hir::MacroDef` now implements `TryToNav` not `ToNav`
as this allows us to handle `HasSource::source` now returning an option.
Assist vs UnresolvedAssist split doesn't really pull its weight. This
is especially bad if we want to include `Assist` as a field of
diagnostics, where we'd have to make the thing generic.

There is a slight problem with this which is also noted in a FIXME now but `LifetimeParameters` of these ForLifetime where clauses allocate the lifetimes in the corresponding arena as if they were lifetimes of the item itself and not just the clause they belong to.
