Function ps_is_builtin_type_name

func ps_is_builtin_type_name(self: ParserState*) -> bool

Check whether the current token is a builtin type name.

Parameters:

• self: Parser state to inspect.

Returns: true if the current token names a builtin type.

Function ps_is_unambiguous_type_start

func ps_is_unambiguous_type_start(self: ParserState*) -> bool

Check whether the current token sequence can only start a type.

Parameters:

• self: Parser state to inspect.

Returns: true if the lookahead unambiguously starts a type reference.

func ps_parse_call_argument(self: ParserState*) -> ExprId?

Parse one call argument.

Parameters:

• self: Parser state to advance.

Returns: Parsed argument expression, or null on error.

Function ps_parse_expr

func ps_parse_expr(self: ParserState*) -> ExprId?

Parse an expression.

Parameters:

• self: Parser state to advance.

Returns: Parsed expression, or null on error.

Function ps_parse_or_expr

func ps_parse_or_expr(self: ParserState*) -> ExprId?

Parse a logical-or expression.

Parameters:

• self: Parser state to advance.

Returns: Parsed logical-or expression, or null on error.

Function ps_parse_and_expr

func ps_parse_and_expr(self: ParserState*) -> ExprId?
