Struct ContentStore 

pub struct ContentStore { /* private fields */ }

Wraps Oxigraph Store, providing named-graph-aware RDF operations. No other crate should import oxigraph directly.

Implementations

impl ContentStore

pub fn new() -> Result<Self, Box<dyn Error>>

Create a new in-memory content store.

pub fn insert_triple_into( &self, subject: &str, predicate: &str, object: &ObjectValue, graph: &str, ) -> Result<(), Box<dyn Error>>

Insert a triple into the specified named graph.

pub fn query_to_json(&self, sparql: &str) -> Result<Value, Box<dyn Error>>

Execute a SPARQL SELECT or ASK query and return results as JSON.

pub fn load_turtle(&self, path: &Utf8Path) -> Result<(), Box<dyn Error>>

Load a Turtle (.ttl) file into the default graph.

pub fn load_turtle_into( &self, path: &Utf8Path, graph: &str, ) -> Result<(), Box<dyn Error>>

Load a Turtle (.ttl) file into a specific named graph.

pub fn clear(&self) -> Result<(), Box<dyn Error>>

Clear all data from the store.

pub fn export_search_ntriples(&self) -> Result<String, Box<dyn Error>>

Export all triples as N-Triples for client-side SPARQL search.

Includes every triple from every named graph so that custom RDF properties (from [rdf.custom] frontmatter) are queryable in the browser alongside standard schema.org fields.

pub fn export_partitioned_ntriples( &self, partition_fn: &dyn Fn(&str) -> Option<String>, ) -> Result<HashMap<String, String>, Box<dyn Error>>

Export triples grouped by a partition function.

The partition_fn receives (graph_name) and returns an optional partition key. Triples whose graph returns None go into the empty-key bucket (main search.nt). The design tokens graph always partitions to "design-tokens".

pub fn export_turtle(&self) -> Result<String, Box<dyn Error>>

Export all triples (flattened from all named graphs) as NTriples.

This is useful for SHACL validation, which operates on a flat graph.

Trait Implementations

impl Clone for ContentStore

fn clone(&self) -> ContentStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.
