Struct Statement

pub struct Statement { /* private fields */ }

Simple, in-memory implementation of the Statement trait.

Implementations

impl Statement

pub fn new<S, O>(subject: S, predicate: Iri, object: O) -> Self

where S: Into<SubjectNode>, O: Into<ObjectNode>,

pub fn rdf_type<S, O>(subject: S, object: O) -> Self

where S: Into<SubjectNode>, O: Into<ObjectNode>,

pub fn subject(&self) -> &SubjectNode

Return the subject of this statement.

pub fn set_subject(&mut self, subject: SubjectNode)

Set the value of this statement’s subject.

pub fn predicate(&self) -> &Iri

Return the predicate of this statement.

pub fn set_predicate(&mut self, predicate: Iri)

Set the value of this statement’s predicate.

pub fn object(&self) -> &ObjectNode

Return the object of this statement.

pub fn set_object(&mut self, object: ObjectNode)

Set the value of this statement’s object.

pub fn is_nested(&self) -> bool

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

pub fn reify(&self) -> Result<(SubjectNode, Vec<Self>)>

Reify a single statement, returning the list of resulting statements.

Trait Implementations

impl From<&Statement> for SubjectNode

fn from(v: &Statement) -> Self

Converts to this type from the input type.

impl From<Statement> for Collection

impl Hash for 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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Statement

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq<Statement> for ObjectNode

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<Statement> for SubjectNode

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for Statement

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Statement

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
