Trait KeyValueIterable

pub trait KeyValueIterable<Error> {
    type Iterator<'a>: Iterator<Item = Result<(&'a [u8], &'a [u8]), Error>>
       where Self: 'a;
    type IteratorOwned: Iterator<Item = Result<(Vec<u8>, Vec<u8>), Error>>;

    // Required methods
    fn iterator(&self) -> Self::Iterator<'_>;
    fn into_iterator_owned(self) -> Self::IteratorOwned;
}

How to iterate over the key-value pairs returned by a search query.

Required Associated Types

type Iterator<'a>: Iterator<Item = Result<(&'a [u8], &'a [u8]), Error>> where Self: 'a

The iterator that returns key-value pairs by reference.

type IteratorOwned: Iterator<Item = Result<(Vec<u8>, Vec<u8>), Error>>

The iterator that returns key-value pairs by value.

Required Methods

fn iterator(&self) -> Self::Iterator<'_>

Iterates keys and values by reference.

fn into_iterator_owned(self) -> Self::IteratorOwned

Iterates keys and values by value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

type IteratorOwned = DynamoDbKeyValueIteratorOwned

impl<E1, E2, K1, K2> KeyValueIterable<DualStoreError<E1, E2>> for DualStoreKeyValues<K1, K2>

where K1: KeyValueIterable<E1>, K2: KeyValueIterable<E2>,

type Iterator<'a> = DualStoreKeyValueIterator<<K1 as KeyValueIterable<E1>>::Iterator<'a>, <K2 as KeyValueIterable<E2>>::Iterator<'a>> where K1: 'a, K2: 'a

type IteratorOwned = DualStoreKeyValueIteratorOwned<<K1 as KeyValueIterable<E1>>::IteratorOwned, <K2 as KeyValueIterable<E2>>::IteratorOwned>
