LSP server configuration

Fields

command: String

Command to spawn the server. Required when enabled=true, ignored when enabled=false.

enabled: bool

Whether the server is enabled

name: Option<String>

Display name for this server (e.g., “tsserver”, “eslint”). Defaults to the command basename if not specified.

args: Vec<String>

Arguments to pass to the server

auto_start: bool

Whether to auto-start this LSP server when opening matching files If false (default), the server must be started manually via command palette

root_markers: Vec<String>

File/directory names to search for when detecting the workspace root. The editor walks upward from the opened file’s directory looking for any of these markers. The first directory containing a match becomes the workspace root sent to the LSP server.

If empty, falls back to [".git"] as a universal marker. If the walk reaches a filesystem boundary without a match, uses the file’s parent directory (never cwd or $HOME).

env: HashMap<String, String>

Environment variables to set for the LSP server process. These are added to (or override) the inherited parent environment.

language_id_overrides: HashMap<String, String>

Override the LSP languageId sent in textDocument/didOpen based on file extension. Maps file extension (without dot) to LSP language ID string. For example: {"tsx": "typescriptreact", "jsx": "javascriptreact"}

initialization_options: Option<Value>

Custom initialization options to send to the server These are passed in the initializationOptions field of the LSP Initialize request

only_features: Option<Vec<LspFeature>>

Restrict this server to only handle the listed features. Mutually exclusive with except_features. If neither is set, all features are handled.

except_features: Option<Vec<LspFeature>>

Exclude the listed features from this server. Mutually exclusive with only_features. If neither is set, all features are handled.

process_limits: ProcessLimits

Process resource limits (memory and CPU)

Implementations

impl LspServerConfig

pub fn display_name(&self) -> String

Merge this config with defaults, using default values for empty/unset fields.

This is used when loading configs where fields like command may be empty (serde’s default) because they weren’t specified in the user’s config file. Resolve the display name for this server. Returns the explicit name if set, otherwise the basename of the command.

pub fn feature_filter(&self) -> FeatureFilter

Build the FeatureFilter for this server config.

pub fn merge_with_defaults(self, defaults: &LspServerConfig) -> LspServerConfig

Merge this config with defaults, using default values for empty/unset fields.

This is used when loading configs where fields like command may be empty (serde’s default) because they weren’t specified in the user’s config file.

Trait Implementations

impl Clone for LspServerConfig

fn clone(&self) -> LspServerConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LspServerConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LspServerConfig

fn default() -> LspServerConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LspServerConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for LspServerConfig

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for LspServerConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
