Panics

This function will panic for different reasons:

• The tokenstreams are not equal.
• Any tokenstream is no valid rust code.
• rustfmt is not installed or configured wrong.
• It was not possible to create a child process to run rustfmt.
• The output of rustfmt could not be converted to Utf-8.
