Implementors

impl<Sym, PS, PS2, C> ParametricRule for PRule<Sym, PS, PS2, C> where
    Sym: Alphabet,
    PS: ParametricSymbol<Sym = Sym, Param = C::Expr>,
    PS2: ParametricSymbol<Sym = Sym, Param = <C::Expr as Expression>::Element>,
    C: Condition, 

type InSym = PS

type OutSym = PS2

fn apply(&self, psym: &PS2) -> Result<Vec<PS2>, RuleError>

Tries to apply the rule and if applicable, produces a successor.
