Interface of the parser database.

Provided Methods

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

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

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

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

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

Parses a file and returns its AST as an expression. Only used for inline macros expanded code.

fn file_statement_list_syntax<'db>( &'db self, file_id: FileId<'db>, ) -> Maybe<StatementList<'db>>

Parses a file and returns its AST as a list of statements. Only used for inline macros expanded code.

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

Returns the parser diagnostics for this file.
