Struct TripleTermSet 

pub struct TripleTermSet { /* private fields */ }

A collection of triple terms with lookup and filtering operations.

Implementations

impl TripleTermSet

pub fn new() -> Self

Creates a new empty triple term set.

pub fn with_capacity(capacity: usize) -> Self

Creates a triple term set with the given capacity.

pub fn insert(&mut self, term: TripleTerm) -> bool

Adds a triple term to the set. Returns true if the term was not already present.

pub fn len(&self) -> usize

Returns the number of triple terms in the set.

pub fn is_empty(&self) -> bool

Returns true if the set is empty.

pub fn contains(&self, term: &TripleTerm) -> bool

Returns true if the set contains the given triple term.

pub fn iter(&self) -> impl Iterator<Item = &TripleTerm>

Returns an iterator over the triple terms.

pub fn filter_by_predicate(&self, predicate_iri: &str) -> Vec<&TripleTerm>

Filters triple terms by predicate IRI.

pub fn filter_by_subject_iri(&self, subject_iri: &str) -> Vec<&TripleTerm>

Filters triple terms by subject IRI.

pub fn ground_terms(&self) -> Vec<&TripleTerm>

Returns all ground triple terms (no variables).

pub fn remove(&mut self, term: &TripleTerm) -> bool

Removes a triple term from the set. Returns true if the term was present.

pub fn drain(&mut self) -> impl Iterator<Item = TripleTerm> + '_

Drains all triple terms from the set.

pub fn to_triples(&self) -> Vec<Triple>

Converts all triple terms to Triples.

Trait Implementations

impl Clone for TripleTermSet

fn clone(&self) -> TripleTermSet

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TripleTermSet

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

Formats the value using the given formatter.

impl Default for TripleTermSet

fn default() -> TripleTermSet

Returns the “default value” for a type.

impl FromIterator<TripleTerm> for TripleTermSet

fn from_iter<I: IntoIterator<Item = TripleTerm>>(iter: I) -> Self

Creates a value from an iterator.

impl IntoIterator for TripleTermSet

type Item = TripleTerm

The type of the elements being iterated over.

type IntoIter = IntoIter<TripleTerm>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
