Trait Implementations

impl Parser for DefaultParser<'_>

fn nth(&mut self, n: usize) -> Token

Peek the nth token, not including whitespace and comments

fn consume(&mut self)

Consume the current token

fn error(&mut self, e: impl Into<String>)

Reports an error at the current token location

type Checkpoint = Checkpoint

fn start_node_impl( &mut self, kind: SyntaxKind, checkpoint: Option<Self::Checkpoint>, _: NodeToken, )

Can only be called by Self::start_node

fn finish_node_impl(&mut self, _: NodeToken)

Can only be called by Node::drop

fn checkpoint(&mut self) -> Self::Checkpoint

fn start_node(&mut self, kind: SyntaxKind) -> Node<'_, Self>

Enter a new node. The node is going to be finished when The return value of this function is dropped

fn start_node_at( &mut self, checkpoint: Self::Checkpoint, kind: SyntaxKind, ) -> Node<'_, Self>

fn peek(&mut self) -> Token

Same as nth(0)

fn expect(&mut self, kind: SyntaxKind) -> bool

Consume the token if it has the right kind, otherwise report a syntax error. Returns true if the token was consumed.

fn test(&mut self, kind: SyntaxKind) -> bool

If the token if of this type, consume it and return true, otherwise return false

fn until(&mut self, kind: SyntaxKind)

consume everything until reaching a token of this kind
