Module stop_condition 

Composable stop conditions for early termination of stream-based profiling.

A StopCondition describes when to stop; a StopEvaluator is the mutable runtime checker that tracks counters and evaluates the condition after each chunk.

Structs

SchemaStabilityTracker

Tracks consecutive rows where the schema (column types) has not changed. Used by engines to implement SchemaStable stop conditions.

StopEvaluator

Runtime evaluator that checks a StopCondition against accumulated counters.

Enums

StopCondition

A composable condition that can trigger early termination of profiling.

Functions

schema_stable_threshold

Extracts the consecutive_stable_rows threshold from a StopCondition, searching through Any/All composites. Returns None if no SchemaStable variant is present.
