Struct libafl::observers::map::StdMapObserver

pub struct StdMapObserver<'a, T> where
    T: Default + Copy + 'static + Serialize + DeserializeOwned,  { /* fields omitted */ }

The Map Observer retrieves the state of a map, that will get updated by the target. A well-known example is the AFL-Style coverage map.

Implementations

impl<'a, T> StdMapObserver<'a, T> where
    T: Default + Copy + 'static + Serialize + DeserializeOwned, 

#[must_use]

pub fn new(name: &'static str, map: &'a mut [T]) -> Self

Creates a new MapObserver

#[must_use]

pub fn new_owned(name: &'static str, map: Vec<T>) -> Self

Creates a new MapObserver with an owned map

pub unsafe fn new_from_ptr(
    name: &'static str,
    map_ptr: *mut T,
    len: usize
) -> Self

Creates a new MapObserver from a raw pointer

Safety

Will dereference the map_ptr with up to len elements.
