Function shortest_path_with_config

Source 
pub fn shortest_path_with_config<W, FI, FO>(
    ifst: &FI,
    config: ShortestPathConfig,
) -> Result<FO>
where
    FI: ExpandedFst<W>,
    FO: MutableFst<W>,
    W: Semiring + WeightQuantize + Into<<W as Semiring>::ReverseWeight> + From<<W as Semiring>::ReverseWeight>,
    <W as Semiring>::ReverseWeight: WeightQuantize + WeaklyDivisibleSemiring,
Expand description

Create an FST containing the n-shortest paths in the input FST. The n-shortest paths are the n-lowest weight paths w.r.t. the natural semiring order.

§Example

§Input

shortestpath_in

§Output with n=1

shortestpath_out_n_1

§Output with n=2

shortestpath_out_n_2
