Required Methods

fn get<'a>(
    &'a self,
    key: impl Borrow<K::RefBaseType<'a>>
) -> Result<MultimapValueIter<'a, V>, Error>where
    K: 'a,

Returns an iterator over all values for the given key. Values are in ascending order.

fn range<'a, T: RangeBounds<&'a K::RefBaseType<'a>> + 'a>(
    &'a self,
    range: T
) -> Result<MultimapRangeIter<'a, K, V>, Error>

fn len(&self) -> Result<usize, Error>

fn is_empty(&self) -> Result<bool, Error>

Provided Methods

fn iter(&self) -> Result<MultimapRangeIter<'_, K, V>, Error>

Returns an double-ended iterator over all elements in the table. Values are in ascending order.
