Type Definition

34 nested items

struct— One enumerated schema with its computed stats and equivalence class.

equivalence_class*:i64<uint>— Index into PathSchemaDiscovery::equivalence_classes.

index*:i64<uint>— Enumeration index (stable for a given source/target/max_length/allowed_types).

is_dead*:bool— Whether the schema has zero connections.

length*:i64<uint>— Number of steps in the schema.

limit_reached*:bool— Whether the connection limit was reached (results may be incomplete).

schema*:String— Human-readable schema string.

selectivity_pruned*:bool— Whether selectivity-based early termination was triggered.

source*:TypeRef— A reference to an OCEL type: an event type or an object type, by name.

variant 1:struct— An event type with the given name.

variant 2:struct— An object type with the given name.

stats*:SchemaStats— Metrics plus optional throughput for a single schema.

metrics*:SchemaMetrics— Quality metrics for a path schema, computed from its instance connections.

throughput:Option<ThroughputStats>— Event-to-event throughput times, if both endpoints are events.

target*:TypeRef— A reference to an OCEL type: an event type or an object type, by name.

variant 1:struct— An event type with the given name.

variant 2:struct— An object type with the given name.
