Struct lain::driver::FuzzerDriver

pub struct FuzzerDriver<T> { /* fields omitted */ }

Helper to manage fuzzer threads, thread state, and global state.

Methods

impl<T: 'static + Send + Sync> FuzzerDriver<T>

pub fn new(num_threads: usize) -> Self

Instantiates new FuzzerDriver with the specified number of threads and uses the thread-local RNG to generate a seed

pub fn thread_count(&self) -> usize

pub fn set_to_reproduce_mode(
    &mut self,
    start_iteration: u64,
    end_iteration: u64
)

Sets the driver mode to attempt to reproduce a crash. When start_fuzzer is called, the routine will configure each thread's RNG state to match what it was at start_iteration, the threads will begin to run, and end at end_iteration.

pub fn num_iterations(&self) -> usize

Returns the total number of fuzzing iterations overall.

pub fn set_iterations(&self, iterations: usize)

Sets the current iteration

pub fn num_failed_iterations(&self) -> usize

Returns the number of iterations that returned an error result

pub fn set_global_context(&mut self, context: Arc<RwLock<T>>)

pub fn global_context(&self) -> Option<Arc<RwLock<T>>>

pub fn set_seed(&mut self, seed: u64)

Sets the root seed

pub fn seed(&self) -> u64

The root seed

pub fn signal_exit(&self)

Signals that all threads should be exiting

pub fn join_threads(&self)

Waits for all fuzzing threads to join

pub fn mode(&self) -> DriverMode

pub fn check_for_stalled_threads(&self) -> bool

Returns a bool indicating whether any threads have a last execution time > NOW() - timeout

pub fn set_thread_timeout(&mut self, duration: Duration)

Sets the max duration before a thread is flagged as stalled

Trait Implementations

impl<T: 'static + Send + Sync> Default for FuzzerDriver<T>

fn default() -> Self

Instantiates new FuzzerDriver with 1 thread per logical CPU and uses the thread-local RNG to generate a seed
