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.

variant 1:ThroughputStats— Throughput time statistics (seconds) over event-to-event connections.

variant 2:()
