I've noticed that there are various suggestions that rust-analyzer seems
to filter out, even if they make sense.
Here's an example of where it seems like there should be a suggestion,
but there isn't:
It turns out that this specific suggestion is not considered
`MachineApplicable`, which are the only suggestions that rust-analyzer
accepts. However if you read the documentation for `MachineApplicable`,
b3897e3d13/compiler/rustc_lint_defs/src/lib.rs (L27-L29)
then you realize that these are specifically only those suggestions that
rust-analyzer could even automatically apply (in some distant future,
behind some setting or so). Other suggestions that may have some
semantic impact do not use `MachineApplicable`. So all other suggestions
are still intended to be suggested to the user, just not automatically
applied without the user being consulted.
b3897e3d13/compiler/rustc_lint_defs/src/lib.rs (L22-L24)
So with that in mind, rust-analyzer should almost definitely not filter
out `MaybeIncorrect` (which honestly is named horribly, it just means
that it's a semantic change, not just a syntactical one).
Then there's `HasPlaceholders` which basically is just another semantic
one, but with placeholders. The user will have to make some adjustments,
but the suggestion still is perfectly valid. rust-analyzer could
probably detect those placeholders and put proper "tab through" markers
there for the IDE, but that's not necessary for now.
Then the last one is `Unspecified` which is so unknown that I don't even
know how to judge it, meaning that the suggestion should probably also
just be suggested to the user and then they can decide.
So with all that in mind, I'm proposing to get rid of the check for
Applicability entirely.

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.

7375: Add support for running name resolution in block expressions r=jonas-schievink a=jonas-schievink
This adds a `block_def_map` query that runs the name resolution algorithm on a block expression, and returns a `DefMap` that stores links to the parent `DefMap` (either the containing block or the crate-level `DefMap`). Blocks with no inner items return the parent's `DefMap` as-is, to avoid creating unnecessarily long `DefMap` chains.
Path resolution is updated to recurse into the parent `DefMap` after looking up a path in the original `DefMap`.
I've added a few new tests for this, but outside of those this isn't used yet.

7359: ItemTree: store a mapping from blocks to inner items r=jonas-schievink a=jonas-schievink
To do name resolution within block expressions, we need to know which inner items are located inside each block expression. This adds such a mapping to `ItemTree`, replacing the previous one, which was seemingly unused other than to access all the inner items.
This also assigns `AstId`s to block expressions, which is needed to store the mapping in salsa.

7336: Rename `CrateDefMap` to `DefMap` r=matklad a=jonas-schievink
I propose handling local items by computing a `DefMap` for every block expression, using the regular (early) name resolution algorithm. The result of that will be a `DefMap` that has a reference to the parent `DefMap`, which is either the one computed for the containing block expression, or the crate's root `DefMap`. Name resolution will fall back to a name in the parent `DefMap` if it cannot be resolved in the inner block.
The `DefMap`s computed for block expressions will go through a separate query that can be garbage-collected much more aggressively, since these `DefMap`s should be cheap to compute and are never part of a crate's public API.
The first step towards that is to make `CrateDefMap` not specific to crates anymore, hence this rename (if this plans sounds reasonable).

I've noticed a bunch of "main loop too long" warnings in console when

This highlighted a problem: we generally use single `cfg`, while it

7276: Remove map module from la-arena public API r=lnicola a=arzg
It’s unlikely that more items will be added to the module, so it’s simpler for users if `ArenaMap` is re-exported and the module made private.
This doesn’t compile for the same reason that #7275 doesn’t:
> This pull request doesn’t compile because dependencies on la-arena go through crates.io, so existing dependencies on the crate are referencing an old version. As such, this PR will only compile once a new la-arena version has been published.

7110: Deduplicate macros when offering completion r=matklad a=AdnoC
Closes https://github.com/rust-analyzer/rust-analyzer/issues/7081
When iterating over the names within the `hir_def::resolver::Scope` for a module, track what macros are in the `hir_def::item_scope::ItemScope::legacy_macros` collection for the module. When iterating over names from the prelude, do not proccess the name if it had been in the `legacy_macros` collection.
This is implemented with a `FxHashSet` in the `Scope::process_names` function that is populated when iterating over `legacy_macros` and checked when iterating over the prelude.
Alternative implementation could instead query the `legacy_macros` `FxHashMap` directly when processing names in the prelude.
Also, I'd like to add a test for this, but I'm not sure where it could be added.
