   ## Convenience proc which inflates a string containing compressed data.

   ## Passing a nil string will crash this proc in release mode and assert in
   ## debug mode. It is ok to pass a buffer which doesn't contain deflated data,
-  ## in this case the proc won't modify the buffer. To check if data was
-  ## inflated compare the final length of the `buffer` with its original value.
