Struct GraphCapabilities 

pub struct GraphCapabilities {
    pub rdf: RdfCapability,
    pub union_default_graph: bool,
    pub reserved_namespaces: Vec<String>,
}

What a graph store declares about itself, read before writing anything that depends on it.

Fields

rdf: RdfCapability

RDF 1.2 triple terms, or the RDF 1.1 fallback.

union_default_graph: bool

The default graph of a query is the union of all graphs (true on tiramemsu), instead of only the statements outside named graphs (SPARQL’s default). Portable queries use GRAPH and do not depend on it.

reserved_namespaces: Vec<String>

IRI prefixes of predicates the store writes for its own bookkeeping (graph memberships, derivation links). Generic readers, such as annotation decoding, skip them.

Implementations

impl GraphCapabilities

pub fn plain(rdf: RdfCapability) -> Self

Capabilities of a plain SPARQL dataset with the given RDF version.

pub fn is_reserved(&self, predicate: &str) -> bool

True when predicate is in one of the reserved namespaces.
