Trait GraphVisitor 

pub trait GraphVisitor<I: Interpretation> {
    type Ok;
    type Error;

    // Required methods
    fn subject<T>(&mut self, value: &T) -> Result<(), Self::Error>
       where T: ?Sized + LinkedDataResource<I> + LinkedDataSubject<I>;
    fn end(self) -> Result<Self::Ok, Self::Error>;
}

Visitor over the subjects of an RDF graph.

Required Associated Types

type Ok

Value returned once the graph has been entirely visited.

type Error

Error type.

Required Methods

fn subject<T>(&mut self, value: &T) -> Result<(), Self::Error>

where T: ?Sized + LinkedDataResource<I> + LinkedDataSubject<I>,

Visits a subject of the graph.

fn end(self) -> Result<Self::Ok, Self::Error>

Ends the graph visit.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
