Struct EventStatsAtLevels 

pub struct EventStatsAtLevels { /* private fields */ }

Implementations

impl EventStatsAtLevels

pub fn total(&self) -> EventCounters

Returns total number of events (summed over all levels).

Trait Implementations

impl Default for EventStatsAtLevels

fn default() -> EventStatsAtLevels

Returns the “default value” for a type.

impl Display for EventStatsAtLevels

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl StatsCollector for EventStatsAtLevels

fn pre(&mut self)

Called by the search algorithm at the begging of each recursive call (for each position). It enables investigating the shape of the search tree (of depth-first search process). Visiting of each node is finished by calling one of: exact, unknown, db_cut.

fn etc(&mut self)

Called by the search algorithm at the begging of ETC phase.

fn recursive(&mut self)

Called by the search algorithm just before loop that iterates over moves and recursively calls the algorithm.

fn tt_read(&mut self)

Called for each reading from transposition table.

fn const_db_read(&mut self)

Called for each reading from const (end) database.

fn db_skip(&mut self, _nimber: u8)

Called when value (passed nimber) read from database (transposition table or const database) caused skipping position (usually by ETC). Type of database can be find by checking which call, TT_read or const_db_read, directly preceded db_cut.

fn db_cut(&mut self, _nimber: u8)

Called when value (passed nimber) read from database (transposition table or const database) caused pruning. Type of database can be find by checking which call, TT_read or const_db_read, directly preceded db_cut.

fn unknown(&mut self)

Called for each position which was recursively searched, but whose nimber wasn’t established (due to pruning algorithm).

fn exact(&mut self, _nimber: u8)

Called for each position whose nimber (given as parameter) is calculated and writen to TT; called for each writing to TT.

fn reset(&mut self)

Reset statistics.
