Trait libafl::observers::Observer

pub trait Observer<I, S>: Named {
    fn flush(&mut self) -> Result<(), Error> { ... }
    fn pre_exec(&mut self, _state: &mut S, _input: &I) -> Result<(), Error> { ... }
    fn post_exec(&mut self, _state: &mut S, _input: &I) -> Result<(), Error> { ... }
}

Observers observe different information about the target. They can then be used by various sorts of feedback.

Provided methods

fn flush(&mut self) -> Result<(), Error>

The testcase finished execution, calculate any changes. Reserved for future use.

fn pre_exec(&mut self, _state: &mut S, _input: &I) -> Result<(), Error>

Called right before exexution starts

fn post_exec(&mut self, _state: &mut S, _input: &I) -> Result<(), Error>

Called right after execution finished.
