Struct SimpleTripleStore 

pub struct SimpleTripleStore { /* private fields */ }

Lightweight Arrow-native triple store.

Wraps ArrowGraphStore with defaults for namespace and layer, providing a simplified API.

Implementations

impl SimpleTripleStore

pub fn new() -> Self

Create a new empty store with a single “default” namespace and layer 0.

pub fn with_defaults(namespace: &str, layer: Option<u8>) -> Self

Create with custom namespace and layer defaults.

pub fn add( &mut self, subject: &str, predicate: &str, object: &str, confidence: f64, source: &str, ) -> Result<String, StoreError>

Add a triple. Returns the generated triple ID.

pub fn add_batch( &mut self, triples: &[(&str, &str, &str, f64, &str)], ) -> Result<Vec<String>, StoreError>

Add a batch of triples. Returns generated IDs.

pub fn remove(&mut self, triple_id: &str) -> Result<bool, StoreError>

Remove a triple by ID. Returns true if found.

pub fn query( &self, subject: Option<&str>, predicate: Option<&str>, object: Option<&str>, ) -> Result<Vec<StoredTriple>, StoreError>

Query triples matching pattern. None means wildcard (match all).

pub fn count( &self, subject: Option<&str>, predicate: Option<&str>, object: Option<&str>, ) -> usize

Count triples matching pattern.

pub fn get(&self, triple_id: &str) -> Option<StoredTriple>

Get a single triple by ID.

pub fn update_confidence( &mut self, triple_id: &str, confidence: f64, ) -> Result<bool, StoreError>

Update confidence on an existing triple. Returns true if found.

pub fn group_by( &self, field: &str, ) -> Result<HashMap<String, usize>, StoreError>

Group and count triples by a field (“subject”, “predicate”, or “object”).

pub fn stats(&self) -> StoreStats

Get store statistics.

pub fn len(&self) -> usize

Total number of triples.

pub fn is_empty(&self) -> bool

Whether the store is empty.

pub fn inner(&self) -> &ArrowGraphStore

Get a reference to the underlying ArrowGraphStore.

pub fn inner_mut(&mut self) -> &mut ArrowGraphStore

Get a mutable reference to the underlying ArrowGraphStore.

Trait Implementations

impl Default for SimpleTripleStore

fn default() -> Self

Returns the “default value” for a type.
