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.
This also allows us to remove a bunch of wrong Defaults
7068: Add VSCode command to view the hir of a function body r=theotherphil a=theotherphil
Will fix https://github.com/rust-analyzer/rust-analyzer/issues/7061. Very rough initial version just to work out where I needed to wire everything up.
@matklad would you be happy merging a hir visualiser of some kind? If so, do you have any thoughts on what you'd like it show, and how?
I've spent very little time on this thus far, so I'm fine with throwing away the contents of this PR, but I want to avoid taking the time to make this more polished/interactive/useful only to discover that no-one else has any interest in this functionality.

7115: Migrate HasSource::source to return Option r=matklad a=nick96
I've made a start on fixing #6913 based on the provided work plan, migrating `HasSource::source` to return an `Option`. The simple cases are migrated but there are a few that I'm unsure exactly how they should be handled:
- Logging the processing of functions in `AnalysisStatsCmd::run`: In verbose mode it includes the path to the module containing the function and the syntax range. I've handled this with an if-let but would it be better to blow up here with `expect`? I'm not 100% on the code paths but if we're processing a function definition then the source should exist.
I've handled `source()` in all code paths as `None` being a valid return value but are there some cases where we should just blow up? Also, all I've done is bubble up the returned `None`s, there may be some places where we can recover and still provide something.

In an attempt to fix#6052 and #4249 this attempts to detect
if rustfmt is a rustup proxy which isn't installed, and reports
the error message to the user for them to fix.
In theory this ought to be memoised but for now it'll do as-is.
Future work might be to ask the user if they would like us to
trigger the installation (if possible).

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.

Avoid mutation of snapshot's config -- that's spooky action at a
distance. Instead, copy it over to a local variable.
This points out a minor architecture problem, which we won't fix right
away.
Various `ide`-level config structs, like `AssistConfig`, are geared
towards one-shot use when calling a specific methods. On the other
hand, the large `Config` struct in `rust-analyzer` is a long-term
config store.
The fact that `Config` stores `AssistConfig` is accidental -- a better
design would probably be to just store `ConfigData` inside `Config`
and create various `Config`s on the fly out of it.
6993: Clean up descriptions for settings r=matklad a=rherrmann
Use two consecutive newlines (`\n\n`) to actually continue text on a
new line.
Use proper markup to reference related settings.
Consistently format references to files, command line arguments, etc.
as `code`. Format mentions of UI elements in _italic_.
Fix typos, add missing full-stops, add missing default values.

Use proper markup to reference related settings.
Consistently format references to files, editor commands, command line

Fix typos, add missing full-stops, add missing default values.
Curiously, LSP uses different enums for those, and unsurprising and
annoyingly, there are things which exist in one but not in the other.
Let's not repeat the mistake and unify the two things

6761: Make config.rs a single source of truth for configuration. r=matklad a=matklad
Configuration is editor-independent. For this reason, we pick
JSON-schema as the repr of the source of truth. We do specify it using
rust-macros and some quick&dirty hackery though.
The idea for syncing truth with package.json is to just do that
manually, but there's a test to check that they are actually synced.
I'll add something like `rust-analyzer --config-schema` in a follow-up
commit.

There's CLI to print config's json schema:
$ rust-analyzer --print-config-schema
We go with a CLI rather than LSP request/response to make it easier to
incorporate the thing into extension's static config. This is roughtly
how we put the thing in package.json.
6650: Make completion and assists module independent r=matklad a=SomeoneToIgnore

6553: Auto imports in completion r=matklad a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/1062 but does not handle the completion order, since it's a separate task for https://github.com/rust-analyzer/rust-analyzer/issues/4922 , https://github.com/rust-analyzer/rust-analyzer/issues/4922 and maybe something else.
2 quirks in the current implementation:
* traits are not auto imported during method completion
If I understand the current situation right, we cannot search for traits by a **part** of a method name, we need a full name with correct case to get a trait for it.
* VSCode (?) autocompletion is not as rigid as in Intellij Rust as you can notice on the animation.
Intellij is able to refresh the completions on every new symbol added, yet VS Code does not query the completions on every symbol for me.
With a few debug prints placed in RA, I've observed the following behaviour: after the first set of completion suggestions is received, next symbol input does not trigger a server request, if the completions contain this symbol.
When more symbols added, the existing completion suggestions are filtered out until none are left and only then, on the next symbol it queries for completions.
It seems like the only alternative to get an updated set of results is to manually retrigger it with Esc and Ctrl + Space.
Despite the eerie latter bullet, the completion seems to work pretty fine and fast nontheless, but if you have any ideas on how to make it more smooth, I'll gladly try it out.

6524: Add support for loading rustc private crates r=matklad a=xldenis
This PR presents a solution to the problem of making`rustc_private` crates visible to `rust-analyzer`.
Currently developers add dependencies to those crates behind a `cfg(NOT_A_TARGET)` target to prevent `cargo` from building them.
This solution is unsatisfactory since it requires modifying `Cargo.toml` and causes problems for collaboration or CI.
The proposed solution suggested by @matklad is to allow users to give RA a path where the `rustc` sources could be found and then load that like a normal workspace.
This PR implements this solution by adding a `rustcSource` configuration item and adding the cargo metadata to the crate graph if it is provided.
------
I have no idea how this should be tested, or if this code is generally tested at all. I've locally run the extension with these changes and it correctly loads the relevant crates on a `rustc_private` project of mine.

Historically, we intentinally violated JSON-RPC spec here by hard
crashing. The idea was to poke both the clients and servers to fix
stuff.
However, this is confusing for server implementors, and falls down in
one important place -- protocol extension are not always backwards
compatible, which causes crashes simply due to version mismatch. We
had once such case with our own extension, and one for semantic
tokens.
So let's be less adventerous and just err on the err side!
6331: correct hover text for items with doc attribute with raw strings r=matklad a=JoshMcguigan
Fixes#6300 by improving the handling of raw string literals in attribute style doc comments.
This still has a bug where it could consume too many `"` at the start or end of the comment text, just as the original code had. Not sure if we want to fix that as part of this PR or not? If so, I think I'd prefer to add a unit test for either the `as_simple_key_value` function (I'm not exactly sure where this would belong / how to set this up) or create a `fn(&SmolStr) -> &SmolStr` to unit test by factoring out the `trim` operations from `as_simple_key_value`. Thoughts on this?
6342: Shorter dependency chain r=matklad a=popzxc
Continuing implementing suggestions from the `Completion refactoring` zulip thread.
This PR does the following:
- Removes dependency of `completions` on `assists` by moving required functionality into `ide_db`.
- Moves completely `call_info` crate into `ide_db` as it looks like it fits perfect there.
- Adds a bunch of new tests and docs.
- Adds the re-export of `base_db` to the `ide_db` and removes direct dependency on `base_db` from other crates.
The last point is controversial, I guess, but I noticed that in places where `ide_db` is used, `base_db` is also *always* used. Thus I think the dependency on the `base_db` is implied by the fact of `ide_db` interfaces, and thus it makes sense to just provide `base_db` out of the box.
