Struct Graph 

pub struct Graph { /* private fields */ }

Thread-safe Oxigraph wrapper with SPARQL caching. Clone is cheap (shared store).

Implementations

impl Graph

pub fn new() -> Result<Self>

pub fn insert_turtle(&self, turtle: &str) -> Result<()>

pub fn insert_turtle_with_base( &self, turtle: &str, _base_iri: &str, ) -> Result<()>

pub fn insert_turtle_in(&self, turtle: &str, _graph_iri: &str) -> Result<()>

pub fn insert_quad(&self, s: &str, p: &str, o: &str) -> Result<()>

pub fn load_path<P: AsRef<Path>>(&self, path: P) -> Result<()>

pub fn query_cached(&self, sparql: &str) -> Result<CachedResult>

pub fn query(&self, sparql: &str) -> Result<QueryResults>

pub fn query_with_prolog( &self, sparql: &str, prefixes: &BTreeMap<String, String>, base: Option<&str>, ) -> Result<QueryResults>

pub fn query_prepared(&self, q: &Query) -> Result<QueryResults>

pub fn quads_for_pattern( &self, s: Option<&Subject>, p: Option<&NamedNode>, o: Option<&Term>, g: Option<&GraphName>, ) -> Result<Vec<Quad>>

Typed pattern filter (no extra allocs).

pub fn clear(&self) -> Result<()>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
