This commit updates `wasmtime::FuncType` to exactly store an internal `WasmFuncType` from the cranelift crates. This allows us to remove a translation layer when we are given a `FuncType` and want to get an internal cranelift type out as a result. The other major change from this commit was changing the constructor and accessors of `FuncType` to be iterator-based instead of exposing implementation details.
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.
