Trait finalfusion::subword::BucketIndexer

pub trait BucketIndexer: Indexer {
    fn new(buckets: usize) -> Self;
    fn buckets(&self) -> usize;
}

N-Gram indexer with bucketing.

Required methods

fn new(buckets: usize) -> Self

Create a new indexer.

The buckets argument is the number of buckets or the bucket exponent (depending on the implementation).

fn buckets(&self) -> usize

Get the number of buckets.

Depending on the indexer, this may be the actual number of buckets or the bucket exponent.

impl<H> BucketIndexer for HashIndexer<H> where
    H: Default + Hasher, 

fn new(buckets_exp: usize) -> Self
