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

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

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.
