Previously, much of the logic for generating the various objects needed for fuzzing was concentrated primarily in `generators.rs`. In trying to piece together what code does what, the size of the file and the light documentation make it hard to discern what each part does. Since several generator structures had been split out as separate modules in the `generators/` directory, this change takes that refactoring further by moving the structures in `generators.rs` to their own modules. No logic changes were made, only the addition of documentation in a few places.
Fuzzing Infrastructure for Wasmtime
This crate provides test case generators and oracles for use with fuzzing.
These generators and oracles are generally independent of the fuzzing engine
that might be using them and driving the whole fuzzing process (e.g. libFuzzer
or AFL). As such, this crate does not contain any actual fuzz targets
itself. Those are generally just a couple lines of glue code that plug raw input
from (for example) libFuzzer into a generator, and then run one or more
oracles on the generated test case.
If you're looking for the actual fuzz target definitions we currently have, they
live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and
libFuzzer.
