Trait Sensor

pub trait Sensor: SaveToStatsFolder + 'static {
    type Observations;

    // Required methods
    fn start_recording(&mut self);
    fn stop_recording(&mut self);
    fn get_observations(&mut self) -> Self::Observations;
}

A Sensor records information when running the test function, which the fuzzer can use to determine the importance of a test case.

For example, the sensor can record the code coverage triggered by the test case, store the source location of a panic, measure the number of allocations made, etc. The observations made by a sensor are then assessed by a Pool, which must be explicitly compatible with the sensor’s observations.

Required Associated Types

type Observations

Required Methods

fn start_recording(&mut self)

Signal to the sensor that it should prepare to record observations

fn stop_recording(&mut self)

Signal to the sensor that it should stop recording observations

fn get_observations(&mut self) -> Self::Observations

Access the sensor’s observations
