Provided methods

fn get_invoking_state(&self) -> isize

fn set_invoking_state(&self, t: isize)

fn is_empty(&self) -> bool

A context is empty if there is no invoking state; meaning nobody called current context. Which is usually true for the root of the syntax tree

fn get_parent_ctx(
    &self
) -> Option<Rc<<Self::Ctx as ParserNodeType<'input>>::Type>>

fn set_parent(
    &self,
    parent: &Option<Rc<<Self::Ctx as ParserNodeType<'input>>::Type>>
)
