Module libafl::observers

Observers give insights about runs of a target, such as coverage, timing, stack depth, and more.

Modules

• cmp
  The CmpObserver provides access to the logged values of CMP instructions
• concolic
  Concolic Tracing
• list
  List observer
• map
  The MapObserver provides access a map, usually injected into the target
• stacktrace
  the StacktraceObserver looks up the stacktrace on the execution thread and computes a hash for it for dedupe
• stdio
  The StdOutObserver and StdErrObserver observers look at the stdout of a program The executor must explicitly support these observers. For example, they are supported on the crate::executors::CommandExecutor.
• value
  A simple observer with a single value.

Structs

• TimeObserver
  A simple observer, just overlooking the runtime of the target.

Traits

• DifferentialObserver
  A trait for Observers which observe over differential execution.
• DifferentialObserversTuple
  Differential observers tuple, for when you’re using multiple differential observers.
• Observer
  Observers observe different information about the target. They can then be used by various sorts of feedback.
• ObserverWithHashField
  A trait for Observers with a hash field
• ObserversTuple
  A haskell-style tuple of observers
• UsesObserver
  Something that uses observer like mapfeedbacks
• UsesObservers
  Defines the observer type shared across traits of the type. Needed for consistency across HasCorpus/HasSolutions and friends.
