Trait libafl::feedbacks::Feedback[−][src]

pub trait Feedback<I>: Named + Serialize + DeserializeOwned where
    I: Input, {
    fn is_interesting<OT>(
        &mut self, 
        input: &I, 
        observers: &OT, 
        exit_kind: &ExitKind
    ) -> Result<bool, Error>
    where
        OT: ObserversTuple;

    fn append_metadata(
        &mut self, 
        _testcase: &mut Testcase<I>
    ) -> Result<(), Error> { ... }

    fn discard_metadata(&mut self, _input: &I) -> Result<(), Error> { ... }
}

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<OT>(
    &mut self,
    input: &I,
    observers: &OT,
    exit_kind: &ExitKind
) -> Result<bool, Error> where
    OT: ObserversTuple, [src]

is_interesting should return the “Interestingness” from 0 to 255 (percent times 2.55)
