Configuration options for the language server.

Fields

parser_install_directories: Vec<String>

A list of strings representing directories to search for parsers, of the form <lang>.(so|dll|dylib) or tree-sitter-<lang>.wasm.

Supports environment variable expansion of the form ${VAR}.

parser_aliases: BTreeMap<String, String>

A map of parser aliases.

language_retrieval_patterns: Vec<SerializableRegex>

A list of patterns to aid the LSP in finding a language, given a file path. Patterns must have one capture group which represents the language name. Ordered from highest to lowest precedence.

valid_captures: HashMap<String, BTreeMap<String, String>>

A map from query file name to valid captures. Valid captures are represented as a map from capture name (sans @) to a short (markdown format) description. Note that captures prefixed with an underscore are always permissible.

valid_predicates: BTreeMap<String, Predicate>

A map of predicate names (sans # and ?) to parameter specifications.

valid_directives: BTreeMap<String, Predicate>

A map of directive names (sans # and !) to parameter specifications.

diagnostic_options: DiagnosticOptions

Options related to diagnostics

formatting_options: FormattingOptions

Options related to formatting

supported_abi_versions: Option<RangeInclusive<u32>>

An inclusive range of ABI versions supported by your tool. The end of the range must be greater than or equal to the start.

Trait Implementations

impl Clone for Options

fn clone(&self) -> Options

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Options

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

Formats the value using the given formatter.

impl Default for Options

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Options

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Options

fn eq(&self, other: &Options) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Options

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Options

impl StructuralPartialEq for Options
