Trait rustfst::fst_traits::ExpandedFst

source · 
pub trait ExpandedFst: Fst {
    fn num_states(&self) -> usize;
}

Required Methods

Returns the number of states that contains the FST. They are all counted even if some states are not on a successful path (doesn’t perform triming).

Example
use rustfst::fst_traits::{CoreFst, MutableFst, ExpandedFst};
use rustfst::fst_impls::VectorFst;
use rustfst::semirings::{BooleanWeight, Semiring};

let mut fst = VectorFst::<BooleanWeight>::new();

assert_eq!(fst.num_states(), 0);

fst.add_state();
assert_eq!(fst.num_states(), 1);

fst.add_state();
assert_eq!(fst.num_states(), 2);
