Trait Implementations

impl NodeOps for RootNode

RootNode does not want to perform any actual NodeOps as these operations should only be invoked by the Parser on successor nodes.

fn accept<'text>(
    &self,
    _parser: &mut Parser<'text>,
    _token: Token,
    _node_ref: &Rc<Node>
)

Accept this node with the given token as data.

fn acceptable(&self, _parser: &Parser, _node_ref: &Rc<Node>) -> bool

Can this node be accepted in the current parser state? By default, a node can be accepted when it hasn't been seen yet.

fn complete<'text>(&self, _token: Option<Token<'text>>) -> Completion<'text>

A RootNode can not be completed.

fn matches(&self, _parser: &Parser, _token: Token) -> bool

A RootNode can not be matched.
