Instead of doing `cargo check` manually, use rust-analyzer's flycheck:
at the cost of more sophisticated check command configuration, we keep
much less code in Zed, and get a proper progress report.
User-facing UI does not change except `diagnostics_fetch_command` and
`env` settings removed from the diagnostics settings.
Release Notes:
- N/A
Adjusts the way `cargo` and `rust-analyzer` diagnostics are fetched into
Zed.
Nothing is changed for defaults: in this mode, Zed does nothing but
reports file updates, which trigger rust-analyzers'
mechanisms:
* generating internal diagnostics, which it is able to produce on the
fly, without blocking cargo lock.
Unfortunately, there are not that many diagnostics in r-a, and some of
them have false-positives compared to rustc ones
* running `cargo check --workspace --all-targets` on each file save,
taking the cargo lock
For large projects like Zed, this might take a while, reducing the
ability to choose how to work with the project: e.g. it's impossible to
save multiple times without long diagnostics refreshes (may happen
automatically on e.g. focus loss), save the project and run it instantly
without waiting for cargo check to finish, etc.
In addition, it's relatively tricky to reconfigure r-a to run a
different command, with different arguments and maybe different env
vars: that would require a language server restart (and a large project
reindex) and fiddling with multiple JSON fields.
The new mode aims to separate out cargo diagnostics into its own loop so
that all Zed diagnostics features are supported still.
For that, an extra mode was introduced:
```jsonc
"rust": {
// When enabled, Zed runs `cargo check --message-format=json`-based commands and
// collect cargo diagnostics instead of rust-analyzer.
"fetch_cargo_diagnostics": false,
// A command override for fetching the cargo diagnostics.
// First argument is the command, followed by the arguments.
"diagnostics_fetch_command": [
"cargo",
"check",
"--quiet",
"--workspace",
"--message-format=json",
"--all-targets",
"--keep-going"
],
// Extra environment variables to pass to the diagnostics fetch command.
"env": {}
}
```
which calls to cargo, parses its output and mixes in with the existing
diagnostics:

Release Notes:
- Added a way to get diagnostics from cargo and rust-analyzer without
mutually locking each other
- Added `ctrl-r` binding to refresh diagnostics in the project
diagnostics editor context
There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures
- [x] Mac build issue

This PR improves adding and working with icons by using the new
`DerivePathStr` to derive icon paths.
This means paths no longer need to be manually specified, and the
`IconName` and file name will always be consistent between icons.
This PR does not do any work to standardize icons visually, remove
unused icons, or any other such cleanup.

For ssh remoting lsps we'll need to have language server support
factored out of project.
Thus that begins

Fixed certain visual artifacts, related to multi line diagnostics and
block toggle rendering.
Also enabled diagnostics toolbar controls for the experimental view too.

For a long time, we've had problems where diagnostics can end up showing
up inconsistently in different views. This PR is my attempt to prevent
that, and to simplify the system in the process. There are some UX
changes.
Diagnostic behaviors that have *not* changed:
* In-buffer diagnostics update immediately when LSPs send diagnostics
updates.
* The diagnostic counts in the status bar indicator also update
immediately.
Diagnostic behaviors that this PR changes:
* [x] The tab title for the project diagnostics view now simply shows
the same counts as the status bar indicator - the project's current
totals. Previously, this tab title showed something slightly different -
the numbers of diagnostics *currently shown* in the diagnostics view's
excerpts. But it was pretty confusing that you could sometimes see two
different diagnostic counts.
* [x] The project diagnostics view **never** updates its excerpts while
the user might be in the middle of typing it that view, unless the user
expressed an intent for the excerpts to update (by e.g. saving the
buffer). This was the behavior we originally implemented, but has
changed a few times since then, in attempts to fix other issues. I've
restored that invariant.
Times when the excerpts will update:
* diagnostics are updated while the diagnostics view is not focused
* the user changes focus away from the diagnostics view
* the language server sends a `work done progress end` message for its
disk-based diagnostics token (i.e. cargo check finishes)
* the user saves a buffer associated with a language server, and then a
debounce timer expires
* [x] The project diagnostics view indicates when its diagnostics are
stale. States:
* when diagnostics have been updated while the diagnostics view was
focused:
* the indicator shows a 'refresh' icon
* clicking the indicator updates the excerpts
* when diagnostics have been updated, but a file has been saved, so that
the diagnostics will soon update, the indicator is disabled
With these UX changes, the only 'complex' part of the our diagnostics
presentation is the Project Diagnostics view's excerpt management,
because it needs to implement the deferred updates in order to avoid
disrupting the user while they may be typing. I want to take some steps
to reduce the potential for bugs in this view.
* [x] Reduce the amount of state that the view uses, and simplify its
implementation
* [x] Add a randomized test that checks the invariant that a mutated
diagnostics view matches a freshly computed diagnostics view
## Release Notes
- Reworked the project diagnostics view:
- Fixed an issue where the project diagnostics view could update its
excerpts while you were typing in it.
- Fixed bugs where the project diagnostics view could show the wrong
excerpts.
- Changed the diagnostics view to always update its excerpts eagerly
when not focused.
- Added an indicator to the project diagnostics view's toolbar, showing
when diagnostics have been changed.

This PR renames the `IconElement` component to just `Icon`.
This better matches the rest of our components, as `IconElement` was the
only one using this naming convention.
The `Icon` enum has been renamed to `IconName` to free up the name.
I was trying to come up with a way that would allow rendering an
`Icon::Zed` directly (and thus make the `IconElement` a hidden part of
the API), but I couldn't come up with a way to do this cleanly.
