Type Definition

16 nested items
struct— Metrics plus optional throughput for a single schema.
metrics*:SchemaMetrics— Quality metrics for a path schema, computed from its instance connections.
coverage*:f64— Fraction of source-type instances with at least one connection.
exclusivity*:f64— Inverse average fan-in: |distinct targets| / support. High = each target reached by few sources.
path_count*:i64<uint>— Total number of connections.
reach*:f64— Fraction of target-type instances reached.
selectivity*:f64— Inverse average fan-out: 1 / (avg distinct targets per connected source). High = discriminating.
sources_with_paths*:i64<uint>— Number of distinct source entities with at least one connection.
support*:i64<uint>— Number of distinct (source, target) pairs connected.
total_sources*:i64<uint>— Total number of source entities of this type.
throughput:Option<ThroughputStats>— Event-to-event throughput times, if both endpoints are events.
