Implementations

impl<'a> Parser<'a>

pub fn parse_file( db: &'a dyn SyntaxGroup, diagnostics: &mut DiagnosticsBuilder<ParserDiagnostic>, file_id: FileId, text: &'a str, ) -> SyntaxFile

Parses a file.

pub fn parse_file_expr( db: &'a dyn SyntaxGroup, diagnostics: &mut DiagnosticsBuilder<ParserDiagnostic>, file_id: FileId, text: &'a str, ) -> Expr

Parses a file expr.

pub fn parse_syntax_file(self) -> SyntaxFileGreen

pub fn try_parse_module_item(&mut self) -> TryParseResult<ModuleItemGreen>

Returns a GreenId of a node with an Item.* kind (see syntax::node::ast::ModuleItem), or TryParseFailure if a module item can’t be parsed. In case of an identifier not followed by a !, it is skipped inside the function and thus a TryParseFailure::DoNothing is returned.

pub fn try_parse_trait_item(&mut self) -> TryParseResult<TraitItemGreen>

Returns a GreenId of a node with a TraitItem.* kind (see syntax::node::ast::TraitItem), or TryParseFailure if a trait item can’t be parsed.

pub fn try_parse_impl_item(&mut self) -> TryParseResult<ImplItemGreen>

Returns a GreenId of a node with a ImplItem.* kind (see syntax::node::ast::ImplItem), or TryParseFailure if an impl item can’t be parsed.

pub fn parse_expr(&mut self) -> ExprGreen

Returns a GreenId of a node with an Expr.* kind (see syntax::node::ast::Expr) or a node with kind ExprMissing if an expression can’t be parsed.

pub fn try_parse_match_arm(&mut self) -> TryParseResult<MatchArmGreen>

Returns a GreenId of a node with a MatchArm kind or TryParseFailure if a match arm can’t be parsed.

pub fn try_parse_statement(&mut self) -> TryParseResult<StatementGreen>

Returns a GreenId of a node with a Statement.* kind (see syntax::node::ast::Statement) or TryParseFailure if a statement can’t be parsed.
