Trait matterdb::Iterator

pub trait Iterator {
    fn next(&mut self) -> Option<(&[u8], &[u8])>;
    fn peek(&mut self) -> Option<(&[u8], &[u8])>;
}

A trait that defines a streaming iterator over storage view entries. Unlike the standard Iterator trait, Iterator in MatterDB is low-level and, therefore, operates with bytes.

Required methods

fn next(&mut self) -> Option<(&[u8], &[u8])>

Advances the iterator and returns a reference to the next key and value.

fn peek(&mut self) -> Option<(&[u8], &[u8])>

Returns a reference to the current key and value without advancing the iterator.
