4207: Add unwrap block assist #4156 r=matklad a=bnjjj
close issue #4156
4253: Remove `workspaceLoaded` setting r=matklad a=eminence
The `workspaceLoaded` notification setting was originally designed to
control the display of a popup message that said:
"workspace loaded, {} rust packages"
This popup was removed and replaced by a much sleeker message in the
VSCode status bar that provides a real-time status while loading:
rust-analyzer: {}/{} packages
This was done as part of #3587
The change in this PR simply renames this setting from `workspaceLoaded` to
`progress` to better describe what it actually controls. At the moment,
the only type of progress message that is controlled by this setting is
the initial load messages, but in theory other messages could also be
controlled by this setting.
Reviewer notes:
* If we didn't like the idea of causing minor breaking to user's config, we could keep the setting name as `workspaceLoaded`
* I think we can now close both #2719 and #3176 since the notification dialog in question no longer exists (actually I think you can close those issues even if you reject this PR 😄 )

4234: Support local_inner_macros r=jonas-schievink a=edwin0cheng
This PR implements `#[macro_export(local_inner_macros)]` support.
Note that the rustc implementation is quite [hacky][1] too. :)

4220: Introduce LowerCtx r=matklad a=edwin0cheng
This PR introduces `LowerCtx` for path lowering.
After this PR, there are only 2 places remains for using deprecated `Path::from_ast`, which is related to `AstTransform` I am not familiar. I would like to change these in another PR by others ;)

4246: Validate uses of self and super r=matklad a=djrenren
This change follows on the validation of the `crate` keyword in paths. It verifies the following things:
`super`:
- May only be preceded by other `super` segments
- If in a `UseItem` then all semantically preceding paths also consist only of `super`
`self`
- May only be the start of a path
Just a note, a couple times while working on this I found myself really wanting a Visitor of some sort so that I could traverse descendants while skipping sub-trees that are unimportant. Iterators don't really work for this, so as you can see I reached for recursion. Considering paths are generally small a fancy debounced visitor probably isn't important but figured I'd say something in case we had something like this lying around and I wasn't using it.

4227: Report invalid, nested, multi-segment crate-paths r=matklad a=djrenren
There was a bug in the previous path-validating code that didn't detect multi-segment paths that started with `crate`.
```rust
// Successfully reported
use foo::{crate};
// BUG: was not being reported
use foo::{crate::bar};
```
This was due to my confusion about path-associativity. That is, the path with no qualifier is the innermost path, not the outermost. I've updated the code with a lot of comments to explain what's going on.
This bug was discovered when I found an erroneous `ok` test which I reported here:
https://github.com/rust-analyzer/rust-analyzer/issues/4226
This test now fails and has been modified, hopefully in the spirit of the original test, to be correct. Sorry about submitting the bug in the first place!

Specifically, things like:
use foo::{crate::bar};
Are now being caught, when before we only caught:
use foo::{crate};

4178: Validate the location of `crate` in paths r=matklad a=djrenren
**This solution does not fully handle `use` statements. See below**
This pull requests implements simple validation of usages of the `crate` keyword in `Path`s. Specifically it validates that:
- If a `PathSegment` is starts with the `crate` keyword, it is also the first segment of the `Path`
- All other usages of `crate` in `Path`s are considered errors.
This aligns with `rustc`'s rules. Unlike rustc this implementation does not issue a special error message in the case of `::crate` but it does catch the error.
Furthermore, this change does not cover all error cases. Specifically the following is not caught:
```rust
use foo::{crate}
```
This is because this check is context sensitive. From an AST perspective, `crate` is the root of the `Path`. Only by inspecting the full `UseItem` do we see that it is not in fact the root. This problem becomes worse because `UseTree`s are allowed to be arbitrarily nested:
```rust
use {crate, {{crate, foo::{crate}}}
```
So this is a hard problem to solve without essentially a breadth-first search. In a traditional compiler, I'd say this error is most easily found during the AST -> HIR conversion pass but within rust-analyzer I'm not sure where it belongs.
Under the implementation in this PR, such errors are ignored so we're *more correct* just not *entirely correct*.
