Required Methods

fn priv_file_syntax_data(&self, file_id: FileId) -> SyntaxData

Should only be used internally. Parses a file and returns the result and the generated ParserDiagnostic.

fn file_syntax(&self, file_id: FileId) -> Maybe<SyntaxNode>

Parses a file and returns its SyntaxNode.

fn file_module_syntax(&self, file_id: FileId) -> Maybe<SyntaxFile>

Parses a file and returns its AST as a root SyntaxFile.

fn file_expr_syntax(&self, file_id: FileId) -> Maybe<Expr>

Parses a file and returns its AST as an expression.

fn file_syntax_diagnostics( &self, file_id: FileId, ) -> Diagnostics<ParserDiagnostic>

Returns the parser diagnostics for this file.
