GetString() generates strings of length GetUint32()

I was trying to work out why struct generation always failed, no matter how large I made the size of the input bytes. The answer was $SUBJECT. I don't have enough RAM for more than a couple of strings to be up to 4GB in size, let alone a statistically significant number of structs containing many such strings each.

What did I miss?

Hit the same thing. I think it is a bug or close to a bug. It also generates completely random bytes which are not necessarily a valid unicode.

My workaround: write a custom GetString(maxLength int), which does roughly (pseudocode)

lengh := abs(int(GetUint64)) % maxLength
bytes := GetNBytes(length)
return string(bytes)

with optional conversion to the ascii range:

for i := range bytes {
	bytes[i] = (bytes[i] % 94) + 32
}

FYI I have concluded that this library isn't ready for prime time. I went looking for correct uses of it, and it turns out that all the references are bogus. This is not the real deal.
