Struct byte_mutator::ByteMutator

pub struct ByteMutator { /* fields omitted */ }

A fixed size buffer with a defined set of stages of mutations that will be applied to the buffer

Methods

impl ByteMutator

pub fn new(bytes: &[u8]) -> Self

Create a new ByteMutator from the provided byte slice. Copies into two internal buffers.

pub fn with_stages(self, stages: Vec<Stage>) -> Self

pub fn new_from_config(bytes: &[u8], config: FuzzConfig) -> Self

Creates a new ByteMutator and consumes the stages configured in config

pub fn remaining_stages(&self) -> usize

Number of outstanding stages

pub fn add_stage(&mut self, stage: Stage)

Add a stage

pub fn next(&mut self)

Advance the mutation one step. Resets outstanding changes, advances the stage state, and mutates using all mutators defined in the stage.

pub fn read(&self) -> &[u8]

Returns an immutable slice of the mutable buffer. Exposes the current state of the ByteMutator.
