Required Methods§

Source

fn before_mutation(&self, trace: &Trace, generation: usize) -> bool

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

Source

fn after_mutation( &self, original: &Trace, mutated: &Trace, record: &MutationRecord, )

Called after mutation is applied

Provided Methods§

Source

fn modify_sites( &self, sites: HashSet<Address>, _trace: &Trace, ) -> HashSet<Address>

Optionally modify the mutation sites before mutation occurs
