pub struct FuzzBitmapControlFlowHandler<M: AsRef<[u8]> + AsMut<[u8]>> { /* private fields */ }

Available on crate feature fuzz_bitmap only.

HandleControlFlow implementor for maintaining fuzzing bitmap

Implementations

impl<M: AsRef<[u8]> + AsMut<[u8]>> FuzzBitmapControlFlowHandler<M>

pub fn new(fuzzing_bitmap: M, filter_range: Option<&[(u64, u64)]>) -> Self

Create a new fuzz bitmap control flow handler.

You can pass things like &mut [u8], Vec<u8>, Box<[u8]>, or even a mmapped structure as fuzzing_bitmap. If you want to give range restrictions, pass filter_range, or you could just pass a None here to indicate that there is no range restrictions.

pub fn diagnose(&self) -> FuzzBitmapDiagnosticInformation

Get diagnose information

type Error = Infallible

Error of control flow handler

type CachedKey = PerCacheBitmapEntries

Available on crate feature cache only.

Cached key returned by take_cache.

fn at_decode_begin(&mut self) -> Result<(), Self::Error>

Callback at begin of decoding.

fn on_new_block( &mut self, block_addr: u64, transition_kind: ControlFlowTransitionKind, cache: bool, ) -> Result<(), Self::Error>

Callback when a new basic block is met.

fn cache_prev_cached_key( &mut self, cached_key: Self::CachedKey, ) -> Result<(), Self::Error>

Available on crate feature cache only.

Merge a previous cached key into cache

fn clear_current_cache(&mut self) -> Result<(), Self::Error>

Available on crate feature cache only.

Clear the cache.

fn take_cache(&mut self) -> Result<Option<Self::CachedKey>, Self::Error>

Available on crate feature cache only.

Collect all currently cached information and generate a cached key. This could clear the cache depending on your implementing logic.

Available on crate feature cache only.

Callback when a given cached key is being reused.
