Trait Implementations

impl Clone for JavaScriptLanguage

fn clone(&self) -> JavaScriptLanguage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JavaScriptLanguage

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

Formats the value using the given formatter.

impl Default for JavaScriptLanguage

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for JavaScriptLanguage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for JavaScriptLanguage

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Language for JavaScriptLanguage

const NAME: &'static str = "javascript"

The name of the language (e.g., “rust”, “sql”).

const CATEGORY: LanguageCategory = LanguageCategory::Programming

The category of the language.

type TokenType = JavaScriptTokenType

The token type used to represent different token and node types in the language.

type ElementType = JavaScriptElementType

The element type used to represent composite structures in the parsed tree.

type TypedRoot = JavaScriptRoot

The root type for the parsed tree that represents the top-level structure of the language.

impl<'config> Lexer<JavaScriptLanguage> for JavaScriptLexer<'config>

fn lex<'a, S: Source + ?Sized>( &self, text: &S, _edits: &[TextEdit], cache: &'a mut impl LexerCache<JavaScriptLanguage>, ) -> LexOutput<JavaScriptLanguage>

Tokenizes the given source text into a sequence of tokens.

impl<'config> Parser<JavaScriptLanguage> for JavaScriptParser<'config>

fn parse<'a, S: Source + ?Sized>( &self, text: &'a S, edits: &[TextEdit], cache: &'a mut impl ParseCache<JavaScriptLanguage>, ) -> ParseOutput<'a, JavaScriptLanguage>

The core parsing entry point.

impl PartialEq for JavaScriptLanguage

fn eq(&self, other: &JavaScriptLanguage) -> 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.

Handles infix and postfix operators.

fn prefix<'a, S>( &self, state: &mut ParserState<'a, L, S>, ) -> &'a GreenNode<'a, L>

where S: Source + ?Sized,

Handles prefix operators and primary expressions.

impl Serialize for JavaScriptLanguage

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for JavaScriptLanguage

impl Eq for JavaScriptLanguage
