Trait returning iterators over subwords and indices.

Defines methods to iterate over the subwords and their corresponding indices as assigned through the given Indexer. The Indexer can allow collisions.

Required methods

fn subword_indices_with_ngrams(
    &'a self,
    min_n: usize,
    max_n: usize,
    indexer: &'b I
) -> Self::Iter

Return an iterator over the subwords and subword indices of a string.

The n-grams that are used are of length [min_n, max_n], these are mapped to indices using the given indexer.
