Struct StatisticsCollector 

pub struct StatisticsCollector<Sc: Score> { /* private fields */ }

Thread-safe collector for solver statistics.

Use this to record statistics during solving. After solving, call into_statistics() to get the final SolverStatistics.

Implementations

impl<Sc: Score> StatisticsCollector<Sc>

pub fn new() -> Self

Creates a new statistics collector.

The start time is recorded when this is called.

pub fn record_move_evaluated(&self)

Records a move evaluation.

Call this each time a move is evaluated, regardless of whether it was accepted.

pub fn record_move_accepted(&self)

Records an accepted move.

Call this when a move is accepted (in addition to record_move_evaluated).

pub fn record_move(&self, accepted: bool)

Records both evaluation and acceptance for a move.

Convenience method when you know the move was accepted.

pub fn record_step(&self)

Records a step completion.

pub fn record_score_calculation(&self)

Records a score calculation.

pub fn record_improvement(&self, score: Sc)

Records a score improvement.

Call this when a new best score is found.

pub fn start_phase(&self, phase_type: impl Into<String>) -> usize

Starts a new phase and returns its index.

Call this at the beginning of each phase.

pub fn end_phase( &self, phase_index: usize, duration: Duration, step_count: u64, moves_evaluated: u64, moves_accepted: u64, starting_score: Option<Sc>, ending_score: Option<Sc>, )

Ends the current phase with the given statistics.

Call this at the end of each phase.

pub fn elapsed(&self) -> Duration

Returns the elapsed time since solving started.

pub fn current_step_count(&self) -> u64

Returns the current step count.

pub fn current_moves_evaluated(&self) -> u64

Returns the current moves evaluated count.

pub fn current_moves_accepted(&self) -> u64

Returns the current moves accepted count.

pub fn current_score_calculations(&self) -> u64

Returns the current score calculation count.

pub fn into_statistics(self) -> SolverStatistics<Sc>

Converts this collector into final statistics.

This consumes the collector and returns the complete statistics.

pub fn snapshot(&self) -> SolverStatistics<Sc>

Takes a snapshot of current statistics without consuming the collector.

Trait Implementations

impl<Sc: Score> Default for StatisticsCollector<Sc>

fn default() -> Self

Returns the “default value” for a type.
