Trait libafl::observers::cmp::CmpObserverMetadata

pub trait CmpObserverMetadata<'a, CM>: SerdeAny + Debug
where
    CM: CmpMap + Debug,
{
    type Data: 'a + Debug + Default + Serialize + DeserializeOwned;

    // Required methods
    fn new_metadata() -> Self;
    fn add_from(
        &mut self,

}

Generic metadata trait for use in a CmpObserver, which adds comparisons from a CmpObserver primarily intended for use with AFLppCmpValuesMetadata or CmpValuesMetadata

Required Associated Types

type Data: 'a + Debug + Default + Serialize + DeserializeOwned

Extra data used by the metadata when adding information from a CmpObserver, for example the original field in AFLppCmpLogObserver

Required Methods

fn new_metadata() -> Self

Instantiate a new metadata instance. This is used by CmpObserver to create a new metadata if one is missing and add_meta is specified. This will typically juse call new()

fn add_from( &mut self, usable_count: usize, cmp_map: &mut CM, cmp_observer_data: Self::Data )

Add comparisons to a metadata from a CmpObserver. cmp_map is mutable in case it is needed for a custom map, but this is not utilized for CmpObserver or AFLppCmpLogObserver.

Object Safety

This trait is not object safe.
