    pub named_triple_counts: HashMap<GraphName, usize>,
    pub total_triple_count: usize,
    pub largest_named_graph: Option<GraphName>,
}

Statistics collected from a NamedGraphManager

Fields

named_graph_count: usize

Number of named graphs (excluding default)

default_graph_triple_count: usize

Number of triples in the default graph

named_triple_counts: HashMap<GraphName, usize>

Per-graph triple counts

total_triple_count: usize

Total triples across all graphs

largest_named_graph: Option<GraphName>

The name of the named graph with the most triples

Implementations

impl GraphStatistics

pub fn average_named_graph_size(&self) -> f64

Returns the average triple count across named graphs (0.0 if none)

pub fn is_empty(&self) -> bool

Returns true if the dataset is completely empty
