Trait Implementations

impl Clone for LoggingHandler

fn clone(&self) -> LoggingHandler

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CrossoverHandler for LoggingHandler

fn before_crossover( &self, _parent1: &Trace, _parent2: &Trace, _generation: usize, ) -> bool

Called before crossover is applied Returns true if crossover should proceed, false to skip

Called after crossover is applied

impl Debug for LoggingHandler

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

Formats the value using the given formatter.

impl Default for LoggingHandler

fn default() -> LoggingHandler

Returns the “default value” for a type.

impl MutationHandler for LoggingHandler

fn before_mutation(&self, _trace: &Trace, _generation: usize) -> bool

Called before mutation is applied Returns true if mutation should proceed, false to skip
