Trait Visitor

pub trait Visitor<I: Interpretation = (), V: Vocabulary = ()> {
    type Ok;
    type Error;

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

RDF dataset visitor.

Required Associated Types

type Ok

Type of the value returned by the visitor when the dataset has been entirely visited.

type Error

Error type.

Required Methods

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

where T: ?Sized + LinkedDataGraph<I, V>,

Visits the default graph of the dataset.

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

where T: ?Sized + LinkedDataResource<I, V> + LinkedDataGraph<I, V>,

Visits a named graph of the dataset.

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

Ends the dataset visit.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<I: Interpretation, V: Vocabulary, S: Visitor<I, V>> Visitor<I, V> for &mut S

Any mutable reference to a visitor is itself a visitor.

type Ok = ()

type Error = <S as Visitor<I, V>>::Error

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

where T: ?Sized + LinkedDataGraph<I, V>,

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

where T: ?Sized + LinkedDataResource<I, V> + LinkedDataGraph<I, V>,

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