}Expand description
Feedbacks evaluate the observers. Basically, they reduce the information provided by an observer to a value, indicating the “interestingness” of the last run.
Required Methods§
sourcefn is_interesting<EM, OT>(
&mut self,
state: &mut S,
manager: &mut EM,
input: &S::Input,
observers: &OT,
exit_kind: &ExitKind
) -> Result<bool, Error>where
EM: EventFirer<State = S>,
OT: ObserversTuple<S>,
fn is_interesting<EM, OT>(
&mut self,
state: &mut S,
manager: &mut EM,
input: &S::Input,
observers: &OT,
exit_kind: &ExitKind
) -> Result<bool, Error>where
EM: EventFirer<State = S>,
OT: ObserversTuple<S>,
is_interesting return if an input is worth the addition to the corpus
Provided Methods§
sourcefn init_state(&mut self, _state: &mut S) -> Result<(), Error>
fn init_state(&mut self, _state: &mut S) -> Result<(), Error>
Initializes the feedback state.
This method is called after that the State is created.
