In rust-analyzer, we avoid defualt impls for types which don't have
sensible, "empty" defaults. In particular, we avoid using invalid
indices for defaults and similar hacks.
Rather than a "Stable" and "Nightly" ABI we instead name ABIs based on
the version of the rust compiler in which they were introduced. We place
these ABIs in a new module - `proc_macro_srv::abis` - where we also add
some mchinery to abstract over ABIs. This should make it easy to add new
ABIs at a later date as the rust compiler evolves.
9535: internal: remove proc macro management thread r=jonas-schievink a=jonas-schievink
Communication with the proc macro server process has always happened one request at a time, so the additional thread isn't really needed (it just forwarded each request, and sent back the response). This removes some indirection that was a bit hard to understand (a channel was allocated and sent over another channel to return the response).
Hope I'm not missing anything here

Note that, while we don't currently have a fuzzy-matching score, it
makes sense to special-case postfix templates -- it's very annoying when
`.not()` gets sorted before `.not`. We might want to move this infra to
fuzzy matching, once we have that!
Before this PR, SourceChange used a bool and CompletionItem used an enum
to signify if edit is a snippet. It makes sense to use the same pattern
in both cases. `bool` feels simpler, as there's only one consumer of
this API, and all producers are encapsulated anyway (we check the
capability at the production site).
One source completion can produce up to two lsp completions.
Additionally, `preselct` and `sort_text` are global properties of the
whole set of completions, so the right granularity here is to convert
many completions.
As a side-benefit, we no loger allocate intermediate vec.
Moving tests to `rust-analyzer` crate allows removing walkdir dependency
from `xtask`. It does seem more reasonable to keep tidy tests outside of
the "build system" and closer to other integration tests.
* Keep codegen adjacent to the relevant crates.
* Remove codgen deps from xtask, speeding-up from-source installation.
This regresses the release process a bit, as it now needs to run the
tests (and, by extension, compile the code).

Now instead of only working on `if let ... {} else {}` if expressions it now works on all of them where the condition expression is the same text-wise.
This includes if let expressions without an else block, in which case a simple `_ => ()` will be generated in the resulting match but also in more complex cases where multiple `if let` expressions are chained.

9423: fix: Resolve attribute paths in attribute highlighting r=Veykril a=Veykril
Attributes have a new highlighting format now, whereas the `#[` `]` tokens are now tagged with `attribute.attribute` like before, but all other idents inside token trees are now `generic.attribute`. If a path in an attribute can't be resolved it will instead get the `builtinAttribute.attribute` tags now as highlighting doesn't know about builtins like `allow` yet, so we don't want to emit unresolved references.

Definition::visibility was implemented in a rather roundabout way -- by
asking the parent module about the effective visibility.
This is problematic for a couple of reasons:
* first, it doesn't work for local items
* second, asking module about visibility of a child is a linear
operation (that's a problem in itself, tracked in #9378)
Instead, lets ask the declared visibility directly, we have all the code
for it, and need only to actually us it.

This story begins in #8384, where we added a smart test for our syntax
highting, which run the algorithm on synthetic files of varying length
in order to guesstimate if the complexity is O(N^2) or O(N)-ish.
The test turned out to be pretty effective, and flagged #9031 as a
change that makes syntax highlighting accidentally quadratic. There was
much rejoicing, for the time being.
Then, lnicola asked an ominous question[1]: "Are we sure that the time
is linear right now?"
Of course it turned out that our sophisticated non-linearity detector
*was* broken, and that our syntax highlighting *was* quadratic.
Investigating that, many brave hearts dug deeper and deeper into the
guts of rust-analyzer, only to get lost in a maze of traits delegating
to traits delegating to macros.
Eventually, matklad managed to peel off all layers of abstraction one by
one, until almost nothing was left. In fact, the issue was discovered in
the very foundation of the rust-analyzer -- in the syntax trees.
Worse, it was not a new problem, but rather a well-know, well-understood
and event (almost) well-fixed (!) performance bug.
The problem lies within `SyntaxNodePtr` type -- a light-weight "address"
of a node in a syntax tree [3]. Such pointers are used by rust-analyzer all
other the place to record relationships between IR nodes and the
original syntax.
Internally, the pointer to a syntax node is represented by node's range.
To "dereference" the pointer, you traverse the syntax tree from the
root, looking for the node with the right range. The inner loop of this
search is finding a node's child whose range contains the specified
range. This inner loop was implemented by naive linear search over all
the children. For wide trees, dereferencing a single `SyntaxNodePtr` was
linear. The problem with wide trees though is that they contain a lot of
nodes! And dereferencing pointers to all the nodes is quadratic in the
size of the file!
The solution to this problem is to speed up the children search --
rather than doing a linear lookup, we can use binary search to locate
the child with the desired interval.
Doing this optimization was one of the motivations (or rather, side
effects) of #6857. That's why `rowan` grew the useful
`child_or_token_at_range` method which does exactly this binary search.
But looks like we've never actually switch to this method? Oups.
Lesson learned: do not leave broken windows in the fundamental infra.
Otherwise, you'll have to repeatedly re-investigate the issue, by
digging from the top of the Everest down to the foundation!
