Document enabling the flatpak rust SDK extension
Just having `org.freedesktop.Sdk.Extension.rust-stable` and `org.freedesktop.Sdk.Extension.llvm15` installed is not enough.
`/usr/lib/sdk/rust-stable/bin` at least needs to be added to the `PATH`.
In the case of VSCodium [ide-flatpak-wrapper](https://github.com/noonsleeper/ide-flatpak-wrapper) in included to do this.
Fix off-by-one error converting to LSP UTF8 offsets with multi-byte char
On this file,
```rust
fn main() {
let 된장 = 1;
}
```
when using `"positionEncodings":["utf-16"]` I get an "unused variable" diagnostic on the variable
name (codepoint offset range `8..10`). So far so good.
When using `positionEncodings":["utf-8"]`, I expect to get the equivalent range in bytes (LSP:
"Character offsets count UTF-8 code units (e.g bytes)."), which is `8..14`, because both
characters are 3 bytes in UTF-8. However I actually get `10..14`.
Looks like this is because we accidentally treat a 1-based index as an offset value: when
converting from our internal char-indices to LSP byte offsets, we look at one character to many.
This causes wrong results if the extra character is a multi-byte one, such as when computing
the start coordinate of 된장.
Fix that by actually passing an offset. While at it, fix the variable name of the line number,
which is not an offset (yet).

internal: Consider ADT generic parameter defaults for unsubstituted layout calculations
For one, this brings back layout information for lifetime generic ADTs (which "regressed" when we started adding lifetimes to chalks-ir), but it also allows layout calculation to work for definitions that don't actually use the generics (where its only used in a `PhantomData` for example)
Changed the completion item source_range to match
the replaced text. Though in VS Code it may not be
disturbing because the snippet is previewed in a
box, but in Helix editor, it's previewed by applying
the main text edit.
pattern analysis: Use contiguous indices for enum variants
The main blocker to using the in-tree version of the `pattern_analysis` crate is that rustc requires enum indices to be contiguous because it uses `IndexVec`/`BitSet` for performance. Currently we swap these out for `FxHashMap`/`FxHashSet` when the `rustc` feature is off, but we can't do that if we use the in-tree crate.
This PR solves the problem by using contiguous indices on the r-a side too.
Fix crate IDs when multiple workspaces are loaded
Previously, we assumed that the crate numbers in a `rust-project.json` always matched the `CrateId` values in the crate graph. This isn't true when there are multiple workspaces, because the crate graphs are merged and the `CrateId` values in the merged graph are different.
This broke flycheck (see first commit), because we were unable to find the workspace when a file changed, so we every single flycheck, producing duplicate compilation errors.
Instead, use the crate root module path to look up the relevant flycheck. This makes `ProjectWorkspace::Json` consistenet with `ProjectWorkspace::Cargo`.
Also, define a separate JSON crate number type, to prevent bugs like this happening again.
feat: Add `rust-analyzer.cargo.allTargets` to configure passing `--all-targets` to cargo invocations
Closes#16859
## Unresolved question:
Should this be a setting for build scripts only ? All the other `--all-targets` I found where already covered by `checkOnSave.allTargets`
Fix tasks in tasks.json
#16839 refactored the representation of tasks inside the VS Code extension. However, this data type is exposed to users, who can define their own tasks in the same format in `tasks.json` or `.code-workspace`.
Revert the data type to have a `command` field rather than a `program` field, and document the different fields. This code is also a little complex, so split out a `cargoToExecution` to handle the Task to Execution conversion logic.
After this change, any tasks.json with a `command` field works again. For example, the following tasks.json works as expected:
```
{
"version": "2.0.0",
"tasks": [
{
"type": "cargo",
"command": "build",
"problemMatcher": [
"$rustc"
],
"group": "build",
"label": "my example cargo build task"
}
]
}
```
Fixes#16943#16949
update: add editor/extension information to bug report template
When attempting to reproduce issues, I encounter difficulties due to differences in versions of LSP clients and editors (such as #16985, #16867, and more)
This sometimes consumes a lot of efforts from contributors to communicate the details about LSP client information. Therefore, I believe adding editor/extension information to the issue template would be helpful for problem reproduction.
