Implementations

impl RLanguage

pub fn new() -> Self

Trait Implementations

impl<'config> Builder<RLanguage> for RBuilder<'config>

fn build<'a, S: Source + ?Sized>( &self, source: &S, edits: &[TextEdit], _cache: &'a mut impl BuilderCache<RLanguage>, ) -> BuildOutput<RLanguage>

Builds the structure from the source text.

impl Clone for RLanguage

fn clone(&self) -> RLanguage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RLanguage

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

Formats the value using the given formatter.

impl Default for RLanguage

fn default() -> RLanguage

Returns the “default value” for a type.

impl HoverProvider<RLanguage> for RHoverProvider

Available on crate feature lsp only.

fn hover( &self, node: &RedNode<'_, RLanguage>, _range: Range<usize>, ) -> Option<Hover>

Returns hover information at the given range.

impl Language for RLanguage

const NAME: &'static str = "r"

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

const CATEGORY: LanguageCategory = LanguageCategory::Programming

The category of the language.

type TokenType = RTokenType

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

type ElementType = RElementType

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

type TypedRoot = RRoot

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

impl<'config> Lexer<RLanguage> for RLexer<'config>

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

Tokenizes the given source text into a sequence of tokens.

impl<'config> Parser<RLanguage> for RParser<'config>

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

The core parsing entry point.

impl PartialEq for RLanguage

fn eq(&self, other: &RLanguage) -> 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 Copy for RLanguage

impl Eq for RLanguage
