// Unsafe is the structure holding the unsafe version of the API.
// The difference between unsafe api and regular api is that the regular API
// copies the buffer passed to Unmarshal functions to a new internal buffer.
// Making it safer because internally GoJay uses unsafe.Pointer to transform slice of bytes into a string.
