All common methods between Visitor and VisitorMut

Required methods

fn last(&self) -> bool[src]

Is this hovered over the last quarterturn in the line

fn alternatives(&self) -> usize[src]

How many alternatives are present on the hovered quarterturn.

fn qturn(&self) -> Option<&QuarterTurn>[src]

View the currently hovered QuarterTurn if it exists

fn next(self) -> Result<Self, VisitingError>[src]

Move the visitor one forward

fn into_alternative(self, alt: usize) -> Result<Self, VisitingError>[src]

Move the visitor into one of the current qturns alternatives. Leaves the visitor at the start of the line without any hovered quarterturn.
