Trait domain::base::name::ToLabelIter

pub trait ToLabelIter<'a> {
    type LabelIter: Iterator<Item = &'a Label> + DoubleEndedIterator + Clone;
    fn iter_labels(&'a self) -> Self::LabelIter;

    fn len(&'a self) -> usize { ... }
    fn starts_with<N: ToLabelIter<'a> + ?Sized>(&'a self, base: &'a N) -> bool { ... }
    fn ends_with<N: ToLabelIter<'a> + ?Sized>(&'a self, base: &'a N) -> bool { ... }
}

A type that can produce an iterator over its labels.

This trait is used as a trait bound for both ToDname and ToRelativeDname. It is separate since it has to be generic over the lifetime of the label reference but we don’t want to have this lifetime parameter pollute those traits.

Associated Types

type LabelIter: Iterator<Item = &'a Label> + DoubleEndedIterator + Clone

The type of the iterator over the labels.

This iterator types needs to be double ended so that we can deal with name suffixes. It needs to be cloneable to be able to cascade over parents of a name.
