Trait Implementations

impl<I: Clone + Interner> Clone for Literal<I>[src]

impl<I: Debug + Interner> Debug for Literal<I>[src]

impl<I: Interner> Eq for Literal<I>[src]

impl<I: Interner> Fold<I> for Literal<I>[src]

type Result = Literal<I>

The type of value that will be produced once folding is done. Typically this is Self, unless Self contains borrowed values, in which case owned values are produced (for example, one can fold over a &T value where T: Fold, in which case you get back a T, not a &T). Read more
