--
[[rust-analyzer.cachePriming.numThreads]]rust-analyzer.cachePriming.numThreads (default: `0`)::
+
--
How many worker threads to handle priming caches. The default `0` means to pick automatically.
--
[[rust-analyzer.cargo.allTargets]]rust-analyzer.cargo.allTargets (default: `true`)::
+
--
Pass `--all-targets` to cargo invocation.
--
[[rust-analyzer.cargo.autoreload]]rust-analyzer.cargo.autoreload (default: `true`)::
+
--
Automatically refresh project info via `cargo metadata` on
`Cargo.toml` or `.cargo/config.toml` changes.
--
[[rust-analyzer.cargo.buildScripts.enable]]rust-analyzer.cargo.buildScripts.enable (default: `true`)::
+
--
Run build scripts (`build.rs`) for more precise code analysis.
--
[[rust-analyzer.cargo.buildScripts.invocationLocation]]rust-analyzer.cargo.buildScripts.invocationLocation (default: `"workspace"`)::
+
--
Specifies the working directory for running build scripts.
- "workspace": run build scripts for a workspace in the workspace's root directory.
  This is incompatible with `#rust-analyzer.cargo.buildScripts.invocationStrategy#` set to `once`.
- "root": run build scripts in the project's root directory.
This config only has an effect when `#rust-analyzer.cargo.buildScripts.overrideCommand#`
is set.
--
[[rust-analyzer.cargo.buildScripts.invocationStrategy]]rust-analyzer.cargo.buildScripts.invocationStrategy (default: `"per_workspace"`)::
+
--
Specifies the invocation strategy to use when running the build scripts command.
If `per_workspace` is set, the command will be executed for each workspace.
If `once` is set, the command will be executed once.
This config only has an effect when `#rust-analyzer.cargo.buildScripts.overrideCommand#`
is set.
--
[[rust-analyzer.cargo.buildScripts.overrideCommand]]rust-analyzer.cargo.buildScripts.overrideCommand (default: `null`)::
+
--
Override the command rust-analyzer uses to run build scripts and
build procedural macros. The command is required to output json
and should therefore include `--message-format=json` or a similar
option.

If there are multiple linked projects/workspaces, this command is invoked for
each of them, with the working directory being the workspace root
(i.e., the folder containing the `Cargo.toml`). This can be overwritten
by changing `#rust-analyzer.cargo.buildScripts.invocationStrategy#` and
`#rust-analyzer.cargo.buildScripts.invocationLocation#`.

By default, a cargo invocation will be constructed for the configured
targets and features, with the following base command line:

```bash
cargo check --quiet --workspace --message-format=json --all-targets
```
.
--
[[rust-analyzer.cargo.buildScripts.rebuildOnSave]]rust-analyzer.cargo.buildScripts.rebuildOnSave (default: `true`)::
+
--
Rerun proc-macros building/build-scripts running when proc-macro
or build-script sources change and are saved.
--
[[rust-analyzer.cargo.buildScripts.useRustcWrapper]]rust-analyzer.cargo.buildScripts.useRustcWrapper (default: `true`)::
+
--

+
--
List of cfg options to enable with the given values.
--
[[rust-analyzer.cargo.extraArgs]]rust-analyzer.cargo.extraArgs (default: `[]`)::
+
--
Extra arguments that are passed to every cargo invocation.
--
[[rust-analyzer.cargo.extraEnv]]rust-analyzer.cargo.extraEnv (default: `{}`)::
+
--
Extra environment variables that will be set when running cargo, rustc
or other commands within the workspace. Useful for setting RUSTFLAGS.
--
[[rust-analyzer.cargo.features]]rust-analyzer.cargo.features (default: `[]`)::
+
--
List of features to activate.

Set this to `"all"` to pass `--all-features` to cargo.
--

+
--
Whether to pass `--no-default-features` to cargo.
--
[[rust-analyzer.cargo.sysroot]]rust-analyzer.cargo.sysroot (default: `"discover"`)::
+
--
Relative path to the sysroot, or "discover" to try to automatically find it via
"rustc --print sysroot".

Unsetting this disables sysroot loading.

This option does not take effect until rust-analyzer is restarted.
--
[[rust-analyzer.cargo.sysrootQueryMetadata]]rust-analyzer.cargo.sysrootQueryMetadata (default: `false`)::
+
--
Whether to run cargo metadata on the sysroot library allowing rust-analyzer to analyze
third-party dependencies of the standard libraries.

This will cause `cargo` to create a lockfile in your sysroot directory. rust-analyzer
will attempt to clean up afterwards, but nevertheless requires the location to be
writable to.
--
[[rust-analyzer.cargo.sysrootSrc]]rust-analyzer.cargo.sysrootSrc (default: `null`)::
+
--
Relative path to the sysroot library sources. If left unset, this will default to
`{cargo.sysroot}/lib/rustlib/src/rust/library`.

This option does not take effect until rust-analyzer is restarted.
--
[[rust-analyzer.cargo.target]]rust-analyzer.cargo.target (default: `null`)::
+
--
Compilation target override (target triple).
--
[[rust-analyzer.cargo.targetDir]]rust-analyzer.cargo.targetDir (default: `null`)::
+
--
Optional path to a rust-analyzer specific target directory.
This prevents rust-analyzer's `cargo check` and initial build-script and proc-macro
building from locking the `Cargo.lock` at the expense of duplicating build artifacts.

Set to `true` to use a subdirectory of the existing target directory or
set to a path relative to the workspace to use that path.
--
[[rust-analyzer.checkOnSave]]rust-analyzer.checkOnSave (default: `true`)::
+
--
Run the check command for diagnostics on save.
--
[[rust-analyzer.check.allTargets]]rust-analyzer.check.allTargets (default: `null`)::
+
--
Check all targets and tests (`--all-targets`). Defaults to
`#rust-analyzer.cargo.allTargets#`.
--
[[rust-analyzer.check.command]]rust-analyzer.check.command (default: `"check"`)::
+
--
Cargo command to use for `cargo check`.
--
[[rust-analyzer.check.extraArgs]]rust-analyzer.check.extraArgs (default: `[]`)::
+
--
Extra arguments for `cargo check`.
--
[[rust-analyzer.check.extraEnv]]rust-analyzer.check.extraEnv (default: `{}`)::
+
--
Extra environment variables that will be set when running `cargo check`.
Extends `#rust-analyzer.cargo.extraEnv#`.
--
[[rust-analyzer.check.features]]rust-analyzer.check.features (default: `null`)::
+
--
List of features to activate. Defaults to
`#rust-analyzer.cargo.features#`.

Set to `"all"` to pass `--all-features` to Cargo.
--
[[rust-analyzer.check.ignore]]rust-analyzer.check.ignore (default: `[]`)::
+
--
List of `cargo check` (or other command specified in `check.command`) diagnostics to ignore.

For example for `cargo check`: `dead_code`, `unused_imports`, `unused_variables`,...
--
[[rust-analyzer.check.invocationLocation]]rust-analyzer.check.invocationLocation (default: `"workspace"`)::
+
--
Specifies the working directory for running checks.
- "workspace": run checks for workspaces in the corresponding workspaces' root directories.
  This falls back to "root" if `#rust-analyzer.check.invocationStrategy#` is set to `once`.
- "root": run checks in the project's root directory.
This config only has an effect when `#rust-analyzer.check.overrideCommand#`
is set.
--
[[rust-analyzer.check.invocationStrategy]]rust-analyzer.check.invocationStrategy (default: `"per_workspace"`)::
+
--
Specifies the invocation strategy to use when running the check command.
If `per_workspace` is set, the command will be executed for each workspace.
If `once` is set, the command will be executed once.
This config only has an effect when `#rust-analyzer.check.overrideCommand#`
is set.
--
[[rust-analyzer.check.noDefaultFeatures]]rust-analyzer.check.noDefaultFeatures (default: `null`)::
+
--
Whether to pass `--no-default-features` to Cargo. Defaults to
`#rust-analyzer.cargo.noDefaultFeatures#`.
--
[[rust-analyzer.check.overrideCommand]]rust-analyzer.check.overrideCommand (default: `null`)::
+
--
Override the command rust-analyzer uses instead of `cargo check` for
diagnostics on save. The command is required to output json and
should therefore include `--message-format=json` or a similar option
(if your client supports the `colorDiagnosticOutput` experimental
capability, you can use `--message-format=json-diagnostic-rendered-ansi`).

If you're changing this because you're using some tool wrapping
Cargo, you might also want to change
`#rust-analyzer.cargo.buildScripts.overrideCommand#`.

If there are multiple linked projects/workspaces, this command is invoked for
each of them, with the working directory being the workspace root
(i.e., the folder containing the `Cargo.toml`). This can be overwritten
by changing `#rust-analyzer.check.invocationStrategy#` and
`#rust-analyzer.check.invocationLocation#`.

If `$saved_file` is part of the command, rust-analyzer will pass
the absolute path of the saved file to the provided command. This is
intended to be used with non-Cargo build systems.
Note that `$saved_file` is experimental and may be removed in the futureg.

An example command would be:

```bash
cargo check --workspace --message-format=json --all-targets
```
.
--
[[rust-analyzer.check.targets]]rust-analyzer.check.targets (default: `null`)::
+
--
Check for specific targets. Defaults to `#rust-analyzer.cargo.target#` if empty.

Can be a single target, e.g. `"x86_64-unknown-linux-gnu"` or a list of targets, e.g.
`["aarch64-apple-darwin", "x86_64-apple-darwin"]`.

Aliased as `"checkOnSave.targets"`.
--
[[rust-analyzer.check.workspace]]rust-analyzer.check.workspace (default: `true`)::
+
--
Whether `--workspace` should be passed to `cargo check`.
If false, `-p <package>` will be passed instead.
--
[[rust-analyzer.completion.autoimport.enable]]rust-analyzer.completion.autoimport.enable (default: `true`)::
+
--
Toggles the additional completions that automatically add imports when completed.
Note that your client must specify the `additionalTextEdits` LSP client capability to truly have this feature enabled.
--
[[rust-analyzer.completion.autoself.enable]]rust-analyzer.completion.autoself.enable (default: `true`)::
+
--
Toggles the additional completions that automatically show method calls and field accesses
with `self` prefixed to them when inside a method.
--
[[rust-analyzer.completion.callable.snippets]]rust-analyzer.completion.callable.snippets (default: `"fill_arguments"`)::
+
--
Whether to add parenthesis and argument snippets when completing function.
--
[[rust-analyzer.completion.fullFunctionSignatures.enable]]rust-analyzer.completion.fullFunctionSignatures.enable (default: `false`)::
+
--
Whether to show full function/method signatures in completion docs.
--
[[rust-analyzer.completion.limit]]rust-analyzer.completion.limit (default: `null`)::
+
--
Maximum number of completions to return. If `None`, the limit is infinite.
--
[[rust-analyzer.completion.postfix.enable]]rust-analyzer.completion.postfix.enable (default: `true`)::
+
--
Whether to show postfix snippets like `dbg`, `if`, `not`, etc.
--
[[rust-analyzer.completion.privateEditable.enable]]rust-analyzer.completion.privateEditable.enable (default: `false`)::
+
--
Enables completions of private items and fields that are defined in the current workspace even if they are not visible at the current position.
--
