}Expand description
A minimal graph interface for evaluating node expressions.
Required Methods§
Sourcefn objects(&self, subject: &NodeTerm, predicate: &str) -> Vec<NodeTerm>
fn objects(&self, subject: &NodeTerm, predicate: &str) -> Vec<NodeTerm>
Get all objects for a given subject and predicate.
Sourcefn subjects(&self, predicate: &str, object: &NodeTerm) -> Vec<NodeTerm>
fn subjects(&self, predicate: &str, object: &NodeTerm) -> Vec<NodeTerm>
Get all subjects for a given predicate and object.
Sourcefn conforms_to_shape(&self, node: &NodeTerm, shape_iri: &str) -> bool
fn conforms_to_shape(&self, node: &NodeTerm, shape_iri: &str) -> bool
Check if a node conforms to a shape (by IRI).
Sourcefn all_triples(&self) -> Vec<Triple>
fn all_triples(&self) -> Vec<Triple>
Get all triples in the graph.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
