Class Stdio.Buffer()->RewindKey

Description

The return value of Buffer.rewind_on_error() and Buffer.rewind_key()

This object will cause the buffer to unwind to the position it was at when the object was created either when it is released (when it falls out of scope, explicit destruct does not count) or when rewind is called, depending on which function was used to create it.
