}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
fn is_interesting<EM, OT>(
&mut self,
state: &mut S,
manager: &mut EM,
input: &I,
observers: &OT,
exit_kind: &ExitKind
) -> Result<bool, Error> where
EM: EventFirer<I>,
OT: ObserversTuple<I, S>,
fn is_interesting<EM, OT>(
&mut self,
state: &mut S,
manager: &mut EM,
input: &I,
observers: &OT,
exit_kind: &ExitKind
) -> Result<bool, Error> where
EM: EventFirer<I>,
OT: ObserversTuple<I, S>,
is_interesting return if an input is worth the addition to the corpus
Provided methods
Append to the testcase the generated metadata in case of a new corpus item
