Struct ironsea_index_hashmap::IndexDestructured

pub struct IndexDestructured<F, K> where
    K: Clone + Eq + Hash + PartialEq + Ord,  { /* fields omitted */ }

Implementation of ironsea_index::IndexedDestructured.

The index is backed by a std::collections::HashMap.

An ordered std::vec::Vec of keys is maintained, in order to satisfy range queries.

Methods

impl<F, K> Index<F, K> where
    K: Clone + Eq + Hash + PartialEq + Ord, 

pub fn new<I, R>(iter: I) -> Self where
    I: Iterator<Item = R>,
    R: Record<K> + RecordFields<F>, 

Creates a new Index from the provided iterator.

pub fn keys(&self) -> &Vec<K>

Return an ordered list of all keys contained in the index.
