Stackfile

This small program uses a plain file as persistent memory for a stack (LIFO (Last In First Out)) of Strings.

Currently the classic push pop empty operations are supported.

Additional to the main rust implementation there exists a horribly unsafe C++ implementation, which will not be worked on anymore. Still doesn't hurt to keep it around.

Plans

• implement some interfaces to make it interoperable with other rust code
• improve the code
