-// NewFromGoFuzz is a helper function that enables using gofuzz (this
-// project) with go-fuzz (https://github.com/dvyukov/go-fuzz) for continuous
-// fuzzing. Essentially, it enables translating the fuzzing bytes from
-// go-fuzz to any Go object using this library.
-//
-// This implementation promises a constant translation from a given slice of
-// bytes to the fuzzed objects. This promise will remain over future
-// versions of Go and of this library.
-//
-// Note: the returned Fuzzer should not be shared between multiple goroutines,
-// as its deterministic output will no longer be available.
-//
-// Example: use go-fuzz to test the function `MyFunc(int)` in the package
-// `mypackage`. Add the file: "mypacakge_fuzz.go" with the content:
-//
-// // +build gofuzz
-// package mypacakge
-// import fuzz "github.com/google/gofuzz"

-// Funcs adds each entry in fuzzFuncs as a custom fuzzing function.

-// Each entry in fuzzFuncs must be a function taking two parameters.
-// The first parameter must be a pointer or map. It is the variable that
-// function will fill with random data. The second parameter must be a
-// fuzz.Continue, which will provide a source of randomness and a way
-// to automatically continue fuzzing smaller pieces of the first parameter.
-//
-// These functions are called sensibly, e.g., if you wanted custom string
-// fuzzing, the function `func(s *string, c fuzz.Continue)` would get
-// called and passed the address of strings. Maps and pointers will always
-// be made/new'd for you, ignoring the NilChange option. For slices, it
-// doesn't make much sense to  pre-create them--Fuzzer doesn't know how
-// long you want your slice--so take a pointer to a slice, and make it
