Struct StopEvaluator 

pub struct StopEvaluator { /* private fields */ }

Runtime evaluator that checks a StopCondition against accumulated counters.

Create one before the processing loop and call update after each chunk. When it returns true, profiling should stop.

Implementations

impl StopEvaluator

pub fn new(condition: StopCondition) -> Self

pub fn with_estimated_total(self, rows: u64) -> Self

Provide an estimated total row count (enables ConfidenceThreshold).

pub fn update( &mut self, chunk_rows: u64, chunk_bytes: u64, memory_fraction: f64, ) -> bool

Update counters and evaluate the stop condition.

Returns true when profiling should stop.

• chunk_rows: number of rows in the chunk just processed
• chunk_bytes: number of bytes consumed by this chunk
• memory_fraction: current memory usage as a fraction of the limit (0.0..1.0)

pub fn should_stop(&self) -> bool

Returns true if a stop condition has already been triggered.

pub fn truncation_reason(&self) -> Option<TruncationReason>

The reason profiling stopped, mapped to TruncationReason.

pub fn rows_processed(&self) -> u64

Total rows processed so far.

pub fn bytes_consumed(&self) -> u64

Total bytes consumed so far.
