String.getBytes and nippy

[alolis]

Hello,

I wanted to ask if nippy is doing anything special when you freeze-to-bytes a string because I have noticed that if I do this:

(thaw-from-bytes (.getBytes "my-string"))

then it simply won't work even though I expected for strings to work fine. I am curious, what is the reason for this?

Thank you for your time

nippy prepends a type id (an int) to the byte array, so that it knows how to decode it, it would be impossible to "guess" the type otherwise. As a result thaw-from-bytes will only work with byte arrays created using freeze-to-bytes.
