Trait rustfst::algorithms::WeightConverter

pub trait WeightConverter<SI: Semiring, SO: Semiring> {
    // Required methods
    fn tr_map(&mut self, tr: &Tr<SI>) -> Result<Tr<SO>>;
    fn final_tr_map(&mut self, final_tr: &FinalTr<SI>) -> Result<FinalTr<SO>>;
    fn final_action(&self) -> MapFinalAction;
    fn properties(&self, iprops: FstProperties) -> FstProperties;
}

The WeightConverter interfaces defines how a weight should be turned into another one. Useful for changing the semiring of an FST.

Required Methods

fn tr_map(&mut self, tr: &Tr<SI>) -> Result<Tr<SO>>

fn final_tr_map(&mut self, final_tr: &FinalTr<SI>) -> Result<FinalTr<SO>>

fn final_action(&self) -> MapFinalAction

fn properties(&self, iprops: FstProperties) -> FstProperties
