Function rustfst::algorithms::weight_convert

pub fn weight_convert<W1, W2, F1, F2, M>(
    fst_in: &F1, 
    mapper: &mut M
) -> Result<F2> where
    W1: Semiring,
    W2: Semiring,
    F1: ExpandedFst<W1>,
    F2: MutableFst<W2> + AllocableFst<W2>,
    M: WeightConverter<W1, W2>, 

Convert an FST in a given Semiring to another Semiring using a WeightConverter to specify how the conversion should be performed.
