Some algorithms don't change much the Fst. This is the case for ArcMap for instance. For instance, inverting input labels and output labels could be done on a ConstFst but...

- Rust implementation - Python binding

It is possible to add some examples in the python documentation and run them to be sure they are working. Ref : https://docs.python.org/3/library/doctest.html

Currently, the only way to create a `ConstFst` object is to convert it from a `MutableFst` which makes some copies along the way. If the number of states, and arcs...

And use it in RmEpsilon (for now there is a todo!)
