Constant fst::raw::VERSION

pub const VERSION: u64 = 3;

The API version of this crate.

This version number is written to every finite state transducer created by this crate. When a finite state transducer is read, its version number is checked against this value.

Currently, any version mismatch results in an error. Fixing this requires regenerating the finite state transducer or switching to a version of this crate that is compatible with the serialized transducer. This particular behavior may be relaxed in future versions.
