[−][src]Trait sixtyfps_compilerlib::parser::Parser
Associated Types
type Checkpoint: Clone
Required methods
#[must_use = "use start_node_at to use this checkpoint"]fn checkpoint(&mut self) -> Self::Checkpoint
fn finish_node_impl(&mut self, token: NodeToken)
Can only be called by Node::drop
fn start_node_impl(
&mut self,
kind: SyntaxKind,
checkpoint: Option<Self::Checkpoint>,
token: NodeToken
)
&mut self,
kind: SyntaxKind,
checkpoint: Option<Self::Checkpoint>,
token: NodeToken
)
Can only be called by Self::start_node
fn nth(&mut self, n: usize) -> Token
Peek the n'th token, not including whitespaces and comments
fn consume(&mut self)
fn error(&mut self, e: impl Into<String>)
Provided methods
#[must_use = "The node will be finished when it is dropped"]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 drop'ed
(do not re-implement this function, re-implement start_node_impl and finish_node_impl)
#[must_use = "The node will be finished when it is dropped"]fn start_node_at(
&mut self,
checkpoint: Self::Checkpoint,
kind: SyntaxKind
) -> Node<'_, Self>
&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 everyting until reaching a token of this kind
