Trait linera_views::store::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>>;

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.

Object Safety

This trait is not object safe.
