Required Associated Constants

const CODE_ACTION: bool

const HOVER: bool

const LANG: &'static str

const TRIGGERS: &'static [&'static str]

const LEGEND_TYPES: &'static [SemanticTokenType]

const PATTERN: Option<&'static str>

Required Associated Types

type ElementError: Into<SimpleDiagnostic> + Send + Sync + Debug

Provided Methods

fn semantic_token_type(_kind: SyntaxKind) -> Option<SemanticTokenType>

Map a CST syntax kind to a semantic token type for highlighting.

fn semantic_token_spans( kind: SyntaxKind, span: Range<usize>, _text: &str, ) -> Vec<(SemanticTokenType, Range<usize>)>

Map a CST syntax kind + byte span to semantic token spans for highlighting.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
