Struct libafl::feedbacks::map::MapFeedback

pub struct MapFeedback<N, O, R, S, T> { /* private fields */ }

The most common AFL-like feedback type

Implementations

impl<N, O, R, S, T> MapFeedback<N, O, R, S, T>where
    T: PartialEq + Default + Copy + 'static + Serialize + DeserializeOwned + Debug,
    R: Reducer<T>,
    for<'it> O: MapObserver<Entry = T> + AsIter<'it, Item = T>,
    N: IsNovel<T>,
    S: UsesInput + HasNamedMetadata + HasClientPerfMonitor + Debug,

pub fn new(map_observer: &O) -> Self

Create new MapFeedback

pub fn new_tracking(
    map_observer: &O,
    track_indexes: bool,
    track_novelties: bool
) -> Self

Create new MapFeedback specifying if it must track indexes of used entries and/or novelties

pub fn with_names(name: &'static str, observer_name: &'static str) -> Self

Create new MapFeedback

pub fn with_name(name: &'static str, map_observer: &O) -> Self

Creating a new MapFeedback with a specific name. This is usefully whenever the same feedback is needed twice, but with a different history. Using new() always results in the same name and therefore also the same history.

pub fn with_names_tracking(
    name: &'static str,
    observer_name: &'static str,
    track_indexes: bool,
    track_novelties: bool
) -> Self

Create new MapFeedback specifying if it must track indexes of used entries and/or novelties

    _input: &S::Input
) -> Result<(), Error>

Discard the stored metadata in case that the testcase is not added to the corpus
