Trait redb::ReadableMultimapTable

    // Required methods
    fn get<'a>(
        &self,
        key: impl Borrow<K::SelfType<'a>>

}

Required Methods

fn get<'a>( &self, key: impl Borrow<K::SelfType<'a>> ) -> Result<MultimapValue<'_, V>, StorageError>

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

fn range<'a, KR>( &self, range: impl RangeBounds<KR> + 'a ) -> Result<MultimapRange<'_, K, V>, StorageError>

where KR: Borrow<K::SelfType<'a>> + 'a,

Provided Methods

fn iter(&self) -> Result<MultimapRange<'_, K, V>, StorageError>

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