This trait models an RDF statement.

Required methods

fn subject(&self) -> &SubjectNodeRef

Return the subject of this statement.

fn set_subject(&mut self, subject: SubjectNodeRef)

Set the value of this statement’s subject.

fn predicate(&self) -> &IRIRef

Return the predicate of this statement.

fn set_predicate(&mut self, predicate: IRIRef)

Set the value of this statement’s predicate.

fn object(&self) -> &ObjectNodeRef

Return the object of this statement.

fn set_object(&mut self, object: ObjectNodeRef)

Set the value of this statement’s object.

fn factory(&self) -> StatementFactoryRef

Return the factory that creates statements using the same provider as self.

Note that this uses Arc as a reference as factories are explicitly intended for cross-thread usage.

fn literal_factory(&self) -> LiteralFactoryRef

Return the factory that creates literals using the same provider as self.

Note that this uses Arc as a reference as factories are explicitly intended for cross-thread usage.

Provided methods

fn is_nested(&self) -> bool

This statement is considered nested if either subject or object is itself a statement (RDF-star)

Trait Implementations

impl Display for dyn Statement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for dyn Statement

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<dyn Statement + 'static> for dyn Statement

fn eq(&self, other: &dyn Statement) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
