Trait shortcut::idx::RangeIndex[−][src]

pub trait RangeIndex<T>: EqualityIndex<T> {
    fn between<'a>(
        &'a self, 
        _: Bound<&T>, 
        _: Bound<&T>
    ) -> Box<dyn Iterator<Item = usize> + 'a>;
}

A RangeIndex is an index that, in addition to performing efficient equality lookups, can also perform efficient range queries.

Required methods

`fn between<'a>( &'a self, _: Bound<&T>, _: Bound<&T> ) -> Box<dyn Iterator<Item = usize> + 'a>`[src]

Return an iterator that yields the indices of all rows whose value (in the column this index is assigned to) lies within the given Bounds.
