Struct LabelStatistics 

Source 
pub struct LabelStatistics {
    pub node_count: u64,
    pub avg_out_degree: f64,
    pub avg_in_degree: f64,
    pub properties: HashMap<PropertyKey, ColumnStatistics>,
}
Expand description

Statistics for a single label (node type).

Fields§

§node_count: u64

Number of nodes with this label.

§avg_out_degree: f64

Average outgoing degree.

§avg_in_degree: f64

Average incoming degree.

§properties: HashMap<PropertyKey, ColumnStatistics>

Per-property statistics for nodes with this label.
